that bench seat looks very clean. If I wasnt separated by nearly the entire U.S. I would come pick it up lol

Thanks for the heads up will do! me and eaglescout are probably going to be doing another meetup here soon since he has some parts i want and I have some parts he wants so we'll be sure to put out a notice for when thats happening

So for those of you interested in cars other than just Comanches, I'm starting up a sort of car club based in Arizona called the "Dingo Dog Crew" or "Dead Desert Dingos" where I'm finding as many classic or unique vehicles I can from people I know or that live in AZ and I'm featuring them on an Instagram page @dingo_dog_crew . Ive got a few cars/trucks posted up currently with a few more queued but if youre in Arizona and want me to feature your comanche (or any other vehicles you may have that fit the bill) hit me up on there and ill be more than happy to post it with some info and a link to your build page or anything. I'm even currently making up some logos to put on stickers and hopefully this actually goes somewhere because its a really fun past time to talk to other people about their vehicles and take pictures of them. I also have a twitter @deaddesertdingo if thats more your speed but I post the exact same things and pictures on both accounts so you won't miss out on one or the other. If you have any recommendations on where I should go with this or know anyone in AZ that might be interested let me know!

My truck has been up to some mischief recently so I thought Id share some pics. here's a few weekends ago when I met up with some of my buddies to go offroading at Butcher Jones in AZ. My truck fared really well and besides some occasional rubbing i had no problems getting over anything: here's some pics from last weekend when I snuck my truck into a classic car meet that was going on where I worked. All 3 of our trucks being tan was just a coincidence but a very happy one: So thats what Graham Cracker has been up to! Ill post some more pics but if you really want to stay on top of what I'm doing my instagram @piratestaz I'm always posting pics of her :)

Thanks! two tone is always nice with black

Thanks! if only it ran as good as it looked lol

Sorry for not updating for awhile but ive been busy. New fuel sending unit changed nothing except now the pump is quieter which is nice. my truck starting throwing codes finally saying my upstream o2 sensor isnt working properly (Code P0135 and P0132) so maybe thats where my problem lies. It still dies over 2500 rpms but at this point I'm tired of spending money on my truck and until I need to get emissions or something breaks I'm just going to ignore it. Thank goodness it goes away after my truck hits operating temps. A weird issue and one that I still havent solved

I'm getting to the point where I can recreate it pretty consistently now. I know this entire thread has probably made me look like a mad man but I'm 90% sure once I get the new fuel sending unit from saveevryjp itll fix my problems. On a cold start if you accelerate somewhat hard you can feel it misfire and stumble, even more so if the AC is on. Once you pass 2500rpms itll cut out and buck without fail. It will occasionally do it in 1st or 2nd, but always will do it in 3rd or 4th. It goes away completely once the engine is at operating temp. Hopefully once I replace my fuel assembly thatll be the end of it, I know halloween is coming up soon but I'm tired of my truck acting like its haunted.

That does seem super similar to the issue ive been having but i just checked and theres nothing electrical running off my power steering anywhere so I don't think its the same issue

I can imagine the looks on faces of the people around you as you proceeded to fill your washer fluid reservoir with coke

more new developments, it only occurs as soon as I hit 2500rpms, if I stay under that while going up a hill/towing something its fine but as soon as I go over 2500rpms while under load it starts dying and hesitating on me

Ill definitely look into that once I get the new sending unit from saveevryjp!

popped off my muffle and took a look inside the catalytic converter, it didnt look broken up but when you shake the housing you can definitely hear something rattle around inside and the ceramic also moves freely as if its not being held in place. I don't think this is the cause of my issues but I guess it could be attributing to it?

what is the fuel pump ground mod? plug wires look brand new, albeit theres some coolant stains on them from a much earlier problem thts now fixed. i checked that coil and it was just all black and i didn't see any brand names on it. It also looked as old as the engine so I'm assuming it won't kill me to replace that as well.

Later this week Ill be replacing the Battery since mines from 2014, the alternator since I got it tested and they said the voltage regulator failed, and the fuel sending unit in the tank which has the regulator, pump, filter all attached to it. Hopefully this helps or else It looks like Ill be going through all my wiring and checking for shorts/broken wire insulation etc. Also probably going to replace the catalytic converter in the near future.

Some new developments, today was a pretty humid day and the truck once again lost power on the highway, once while getting onto the highway in 3rd around 2500rpms it just stopped and even though I was pressing the gas it went down to idle, after shifting into 4th though it was fine, and at the end of the day coming home on the highway I was going up a hill losing speed in 5th so I downshifted to 4th and it immediately lost power and went to idle even though I was pressing the pedal. Shifted back up to 5th and it was fine (albeit very slow since I hadnt made it up the hill yet.) What a weird little quirk my truck is developiing. My dad thinks its electrical and the humidity is causing it, but what could the humidity be affecting? My oil pressure and alternator gauge readings also went up again like they did in Mexico while it happened. Also worth noting i guess that right before the first time it happened today my speedo was acting wonky and was jumping all over the place, as soon as the bogging stopped the speedo went back to normal. Maybe my truck is just haunted.

lol youre probably right, probably couldnt hurt to replace it

id say a good 20 minutes passed before I started having issues. My catalytic converter is 33 years old but my Muffler is brand new. Its possible tht some rust was shaken loose but I live in AZ and rust is pretty scarce here. Ill check the cat though just to see if theres any loose debris in it and maybe replace it altogether if need be thanks for the tip

I thought itd be quick and easy, I should have known thats never the case >:(

That was the first thing I checked, but I'm 100% positive it wasnt diesel I filled the tank with. The 2 other jeeps I was with also used the same station and same pump and they had 0 issues. My dad was driving behind me the entire time and he said there was never any smoke. Ive already run the tank downa few times and also run some fuel stabilizer and injector cleaner through it but it still gives the occasional lurch while cruising at 65-70 and bogs occasionally in gear/getting up to speed. For the most part the issue has gone away though and I'm hoping its just my pump giving out and replacing it later this week will solve all the issues.

Ive looked my truck up and down and can't figure it out. The electricalish burning smell I was smelling I believe is coming from my power steering pump, as the pump whines and hums pretty gosh darn loud even at idle and while turning now, but everything else looks like its in order.Ill check my coils to see who made them and if youre correct ill replace those. I'm planning on replacing my fuel sending unit/pump assembly anyway to be on the safe side, but other than stuttering/bogging a bit while getting up to speed and the occasional misfire in 3rd or 4th It really hasn't done anything as bad as it did in mexico. The oil smelling like gas is a good point though and Ill definitely check on that. How would gas be getting into the oil though?

It was fun! gotta get some more guys to show up next time

hey thats me

Well that took much less time to locate than I figured it would! Ill Pm you

I renamed the thread to better explain whats goin on, and the original title felt too long. Bit of a long read but I'm stunped so here's everything that has led up to this post, also for clarification my truck is an '86 but the entire powertrain has been swapped with a '96 cherokee, computers and all: This last labor day weekend I took a trip to Mexico, a sort of maiden voyage for my truck as its never gone further than an hour or so. It made it all the way there perfectly fine running in 5th gear 2300-2500rpms with a fully loaded bed of supplies and AC on no problem. However, as soon as I got gas at a pemex station in Mexico (which ill never do again) my truck started having issues. Id be going 65-70 and it would just bog down, lose power, misfire, and jerk back and forth. Even in nuetral if i attempted to rev it would be choppy and try to stall, and sometimes pressing the gas pedal would do nothing and the revs would stay at idle (about 650-700rpm). Temps read normal (even lower that 210 at some points) but i noticed my oil pressure would shoot up from 50-55 to 60-65. My alternator readings also shot up and would read in the middle when previously they read a little bit lower than middle. I would just end up hunting gears and downshifting to keep the revs as high as I could until it went away after about 5 minutes. This would continue to repeat for the rest of the trip in Mexico with it bogging for a solid few minutes before acting normal again for another 10 or so minutes. This really sucked as most of the time I was in the sand but my old girl pulled through every time and I ended up making it to the campsite without getting stuck. 500 miles from home in a different country there wasnt much I could do so i just hoped it was the fuel sending unit acting up and getting to hot and by the time we left to go back home itd be fine again. This was half correct as the day we left it ran normally until we got out of the desert and onto asphalt again, but after 10 minutes of asphalt driving my ac started smelling like something was burning, and straight up died and started blowing hot air. Immediately i turned it and the truck off to inspect under the hood and sure enough I'm definitely smelling some sort of burning smell, but I have no idea what. At this point I can also smell oil when it bogs down, but this is definitely something different that I still have been unable to locate. I thought maybe its overheating and my thermostat is stuck and thus my gauge is reading incorrectly so i took the hood off and put it in the back, after letting it sit for a second i started it back up and continued on my way, checking the AC to make sure it blew cold again (it did) and then turning it off to make sure i wasnt creating needless heat. For the most part it did really good, i drove a solid 45 minutes at speeds of 65 with no issues but as soon as i smelled that burning smell and oil again it started bogging down. This time i said to hell with it and downshifted straight to 3rd at 55mph and 3500rpms. I drove like this for a good few minutes with no issues so i thought maybe it had gone away and shifted into 4th. Nope. Immediately bogging and misfiring and losing power, same for 5th, so back to 3rd it was. I continued in 3rd for awhile with no issues other than my engine sounding like a prop plane before checking again and this time it went into 4th and then 5th with no problem and that continued until i crossed the border. After the border I stopped at a Texaco and filled up 3/4 the tank with their standard unleaded that had techron and put some injector cleaner in as I suspected at this point maybe the gas I got in Mexico was a little watered down or just all around bad. After filling up I made it an entire 275 miles with 0 issues cruising at 70mph until i was about 10 minutes from home and it started bogging down again, only this time it didnt go away. I kicked that trucks butt in those final 10 minutes i tell ya and as bad as i felt about it I just wanted to get home, 2nd gear, 3rd gear, 4th gear, i was just shifting nonstop doing the best i could to keep it at least at 45mph even though it was fighting me the whole time. I finally made it home and the next day i filled up a new tank and added some more injectior cleaner and took it out on the highway where low and behold- nothing happened it drove perfectly. On the way back however after turning it off to get lunch and coming back it started acting up as i was leaving the parking lot and straight up stalled out on me. That burning smell was also present. 2 days since then now and it consistently does it on a cold start if I don't give it a few minutes to warm up and I'm at a total loss for what could have caused this whole ordeal. Clogged fuel filter? Bad gas? Bad alternator? Bad injectors? Bad fuel sending unit/fuel pressure regulator? Not getting a good spark? It also seems like my truck is down on power now too, or rather the pedal isnt as responsive. It accelerates much slower than it was even though now it doesnt even have all the weight in the back from the trip. Thanks for reading this far I'm just having trouble locating the issue as it seems it could be tons of different things. This truck is my daily so ill continue to drive it every day and it seems fine once it warms up but like I said I can't start driving after a cold start (or even a warm start) without giving it a second or else itll misfire/bog down and try to stall. Let me know what you guys think! here's a pic of my truck going "roadkill" as a reward for reading this far:
