no carpets, just floor pan metal under my feet. Hot floor pan metal, but thats planned to be fixed too at some point lol

it was all tuned up just short of being rebuilt last year, only problem is i didnt own it when all that work was done so I'm not 100% sure on if the people who did it, did a good job. Other than this throttle body "issue" i found everything else seems to be in great working order

Do I have a Tach? yes. does it work? well now youre askin a bit much arent ya. All jokes aside on the highway in 5th gear at 65mph that engine is well above 2k rpm, id say 3500 if i had to guess. I'm running 31s and the axles are out of a 96 cherokee and I'm not sure yet if its been regeared but all signs point to yes.

ill have to try that, if i were to guess id say its probably 3.55 but ill definitely find out

i know about the low rpm performance, but on the highway she struggles to maintain even 55-60 so i was thinking if its not opened all the way that could be the culprit. and yes I feel like 18-19mpg is insane for this truck since my old one got 16-17ish, although this one is a manual so maybe thats why.

good idea thank you

i do not believe so, I bought it after the swap and I can't find any information on if it was geared up other than the fact that 1st gear is so low that i normally start in second, I'm able to let off the clutch in first without giving it any gas, and ive climbed some steep hills with no effort at all, and I shift into 5th gear at 45mph. All of that points to low gearing to me but like I said I'm not 100%

EDIT: for some clarification, after talking to some people down below this is pretty normal and everything I'm experiencing can probably be traced to the fact that I might have bigger gearing than stock (need to check that) and I'm running 31's on a truck thats 33 years old lol. I made this thread because I had a 94 4cyl wrangler awhile back that had no issues with getting up to speed or maintaining 65-70 that was on 32s so I thought it was odd that my 6cyl was having trouble. But also the wrangler had stock gearing and a much shorter wheel base so I'm sure thats where the difference lies So I discovered after having someone press in my gas pedal all the way, that my throttle body can still open about a good 1/4th (maybe even a half) inch further. Is this normal because I don't feel like it is and it would explain why A.) Ive been averaging about 18-19mpg, and B.) Why my truck is so gosh darn dirt slow. How would I go about adjusting this as ive never dealt with any throttle stuff before.

watch your language man (lol)

thank you for even specifying the part number, I'm definitely going to be replacing that asap

If you did id be eternally grateful, gotta rep the forums!

June 12th 2019: I did what most people on this forum can only dream of achieving. I located and purchased an OEM (as far as I can tell) Comanche long bed camper shell! Its in great condition, fits snugly and it only cost me 300$. My plans with this shell are to get it all sanded down and spray it with some quality black bed liner to match the other black accents on my truck. I might also look into lizard skin coating the inside to make sure the temps don't get too high since I do live in AZ and black is the worst color for heat. My only regret with this is that now my Comanche Club sticker is all covered up but maybe that gives me an excuse to not have it on all the time.

New taillights, fix a cooling issue (she gets really hot in the AZ sun I'm talkin 235-240) and maybe get some beefier axles and a spring over axle lift kit. Engine is pretty solid for the most part luckily.

May 27th 2019: Next up was something I was so glad to get done, the exhaust. Previously the exhaust was cut out right behind the catalytic converter which meant inside the cab it was nearly impossible to talk to the person next to you. I fixed this by clamping on a flowmaster muffler and using alfa romeo exhaust pipe (idk either my uncle had it in his garage and said I could use it) I piped it all the way to the back of the truck where not only does it sound very nice, but the droning noise from the engine is finally gone. Id like to preface these photos with the fact that I attended welding classes for two years of my life, but the harbor freight welder I was using refused to cooperate and the end result wasnt so pretty lol.

May 19th 2019: Crucial frame structural integrity and flex testing, very important. Passed with flying colors.

May 15th 2019: Truck felt a little slow so I added some decals for +5 HP.....jk, I just thought it looked much better like this. Decals came from prop_kulture on ebay and they fit perfectly! (I did mess up one of the e's though but thats on me) I also found some really tiny hooks at my work that I thought looked funny so I put them on for laughs.

May 12th 2019: First up on the list was restoring the badges to their former glory, I did this by masking off the chrome, lightly sanding down the black border and then just hitting it with a layer of glossy black spray paint and letting it dry. After I attempted to buff and polish the chrome bits with what I had on hand and stuck them on using 3M emblem adhesive. I'm pretty satisfied with how it turned out!

I decided it was finally time to start one of these for my truck since every day it seems like I'm adding more and more things and I want to make sure I keep track of when I did it. to start, here's some info on good ol' Graham Cracker: 1986 Jeep Comanche "Graham Cracker" 4.0 High Output I6 / AX15 transmission / NP231 t-case / Front Axle is a Dana 30, Rear Axle is a Dana 35 Build date: 3/19/86 Current Location: Chandler, Arizona Status: Daily Driver and weekend rig So this is my second Jeep Comanche. I foolishly traded my old one for a Honda Accord in an attempt to get better gas mileage and have regretted my decision ever since. I'm not kidding either ask anybody around me and not a single day passed where I didnt bring up my old "Dusty Duchess". I missed it so much that I sold a perfectly good toyota tacoma with barely 100k miles (30k of which were from me) and bought the best looking MJ I could find. That brings us to what I have today; body and Chassis are the 86 Comanche MJ, literally everything else is out of a 1996 Cherokee XJ. Over 10k in this truck and it runs strong. 4.5 inch procomp lift (not spring over axle) sitting on 31's. Long bed with a JCR steel bumper and historic plates. Original 10 slot grill with an all black/tan interior, american racing wheels, and the underside is bedlined to prevent rust/debris damage. Hood has hood pins instead of a latch, and theres an electric fan installed. The paint job is Maaco but its the most expensive package so here's to hoping it will last more than 2 years. Pictures below are from the day I first took it home on May 4th 2019!

I always heard that. "Verify with an IR gun" but youre the first person to tell me where to look so thank you. I guess the thermostat housing is common sense though lol.

Pretty much the entire cooling system was replaced last January, where should i begin to look to improve temps? Maybe add another electric fan that i can turn on manually?

These arent startup temps, more like after driving 20 minutes and sitting in the target parking lot for a minute while i wait for my girlfriend to come out. Usually i shut it off while i wait but the other day i let it stay on to see how it would handle it. If its startup or while I'm drivinh the temps usually sit around 175/180. Also pretty much all of the cooling components (pump/rad/coolant/etc) was all replaced last January so its only a year old.

Yo, so ive noticed at idle my truck will get to about 215-220 temp and then the electric fan will kick on and lower it to 210. After that it stays at about 210 pretty consistently. Are these temperatures too much for idle? Is it fine if I'm idling at that temp?

This was my first comanche a few years back. I was young and drove alot so the gas killed me and i wanted something better on fuel. Well along comes this dude who offers to trade his honda accord and I think "perfect". Long story short the Honda blew up 4 days later and literally every single day since the trade i regretted getting rid of my beloved 'dusty duchess'. Now I have my good ol 'Graham Cracker' that I promised no matter what I would always keep, and to be honest its a much better truck than my first mj lol. ANYWAY, maybe one of you guys out there want to pick up my old dusty duchess, carry on the legacy from the guy that ripped me off. (Although i wouldn't, i paid 600$ for it originally, put a 500$ lift kit on it with 400$ tires and called it a day, unless they replaced the axles with pure gold youd be getting ripped off) https://www.facebook.com/marketplace/item/183254915950241/

Yea our old wrangler had 33's and it was atrocious on the highway. My friends '73 F250 has 37s and 45mph feels like a deathtrap
