AMC-MJ

it started acting up again today put 5G of fuel into it and another bottle of Iso alky, after 40 mile of stumbling and bucking i got it out to the farm unload the bed and removed the topper YAy Looks Killer cool ! then from Farm 1 to Farm 2 it started running great but wouldn't idle kept stalling dead once ya let off the throttle . . . Smelt horribly like gasoline, Did the O2 Sensor test yup sure enough POS :fs1: is dead doing nothing :wall: So ordered a new one should be in Tuesday. It acted up the whole way home flipping between running and not idling to idling and stumbley bumbley running . . . Mike

Well, I can safely say the D35 is plenty strong, tho most say the 2.5 is a pooch or a dog, then they must be running the wrong set up behind it. My 2.5 is a strong quick truck ... Maybe its the AX-4 and 3.73s making it go but 0-75mph it screams . . . Right now I got 1,200lbs in the bed and I put on some 235 MT's and it walks right up to 55mph smoothly and quickly . . . I'm plenty happy with my truck ! Mike

I have yet to have my D35 come apart, and through my whole water in fuel replace a bunch of random parts getting place ordeal that D35 got abused hard core . . . :cheers: to the bullet proff D35 :cheers: ya know every body's going to post how they hate it'll be the stand out and support it . . . tho i would rather have an :bowdown: AMC-20 4.44 gears :banana: T-5 AMC-V8 ;) But 2.5 AX-4 3.73 d35 works for now 8) Mike

:cheers: we went for a ride today, darn door latch striker fell inside the cab so now i have bungee cord wrapt around my steering column holding the door shut :hmm: But none the less she run's perfectly :cheers: New meats: viewtopic.php?f=7&t=21829 Mike

Cool thank's, i'm sure it'll be fine tray or no tray just gotta keep gas in it . . . Anywho, I got gutsy and rather then get a ride to the bank i drove the Jeep it ran great all the way there and back ! pulled them 235's just fine even with all the weight in the bed no power issues, Man do them Nice M/T's have a nice hum to them . . . Water in the fuel was my issue trucks fixed :thumbsup: Mike

:dunno: "TRAY" :???: Mike

I did a general search so it would list all Comanche fuel tank's . . . tanks: http://www.partstrain.com/store/?PN=929 ... ersal:0%29 not sure where to post this but, it seems to be a good site for MJ's . . . Mike

It's not a bad price i don't think some are more expensive but they have longer coverage of warrenty's they have both the carbbed and EFI tank's . . . Mike

This truck gets driven every day, around my area we have alternate side parking mid Nov-mid Mar . . . So its been a real treat try to limp it from side to side only being able to idle it through this hole ordeal . . . I figured i'm going through the fuel system any how may as well look at the fuel tank . . . Gas TanK: http://www.partstrain.com/store/details ... 70104.html Mike

:fs1: No i was bragging about using no alky fuel, Some body else was arguing with some body else over weather or not that alky or non alky fuel could be had . . . I simply mentioned the Gas station on my block sold non alky fuel so that's what i was burning, not because f the fuel type but the mere location of the station . . . I know i only put about a 1/2 tank of fuel in my truck at a time, Cause the tank leaks when i fill it up 5/8 of a tank as i mentioned months and months ago ;) . . . Holy Kat's leaky tank + winter weather + my symptoms = :fs1: I need to get a ne rubber seal for the sending unit :fs1: Now i feel stupid :doh: I bet I got WATER :thumbsup: Say where can i get a new gas tank for this truck ? I'm into it this deep i may as well get a new one so there is no more surprises . . . Mike

:D Beautyful have you sen mine yet ? . . . Mike

:wall: Well i changed the fuel filter, added 5.2 gallons of fresh fuel, and a yellow bottle of "HEAT" and it after a while of stumbling and bumbling around i now have the use of idle up to 1/4 throttle with out any malfunction's but once i get around 1/2ish throttle it start to stumble and bumble but it doesn't really bog now but i never got on it any to see how it performed in them 3/4-WOT zone . . . Good news is it went for useless to marginally drivable ;) Progress boys & girls progress gotta make you all feel good i'm happy at a sign of forward progress instead of another get no where money investment :clapping: I think i may have a bad fuel tank or sending unit seal :???: :dunno: :???: I read that some place where a person had an issue like this turned out he had a rusty top side of the tank and dried out rotten sender seal :ack: Could such a thing be happening here :???: :dunno: :???: Can moisture be getting into my fuel tank ? . . . Mike

while doing a quick internet search of my symptom's i found 4 reoccurring fixes . . . 1. TPS on EFI engines & accelerator pump on carbbed engines. 2. Vacuum leaks. 3. air intake charge temp sender. 4. O2 sensor. 5. pour fuel/ clogged filter listed a few times. Mike

We tested and tuned the TPS best we could get for numbers where .81V & 4.14V best it would get for the M/T it call for a .80V & 5.0V . . . It ran great for almost a whole lap around the block then it went to stumbling but instead bogging & dogging till it stalled out 3 out of 8 times it actually caught itself and reved up then stumbled and bumbled some more instead bogging right to dead stall or idle . . . Watery Crappy Fuel ? :dunno: ? Mike

I'm sure it did but its been gone so nope it can't be plugged up so that's cool. Thanks for the link ill load it and learn. Mike

There isn't a Cat ? Truck never had one when I got it ? When the exhaust shop put the new one on they didn't install one either. The way it was it didn't appear there ever was one ? There was no cobbled pipe making it like it was removed by a previous owner . . . Ok I simply installed the new TPS as the old was set. If there is a proper way of installing the TPS I'd like to know about it . Mike

Throttle Position Sensor is brand new just changed it yesterday ! I took my fuel pressure tester back to the store as it wouldn't adapt to this truck and got the TPS with the money ! If the Crank Position Sensor was bad the engine would simply not run or so i was told by many. The second the Map sensor is unplugged the engine stalls which i was told ment it was fine. As for the rest I don't know what they are . . . You gotta remember i'm used to driving 1950's 60's 70's truck's Carburated engine's with manual choke's . . . even the automatic choked carb's confuse me from time to time EFI is well beyond my understanding but i have owned a few Injected unit's i personally liked the TBI over the TPI, MPI, and SFI system's TBI seemed to be more stable and less trouble some till now . . .This is my first TBI related malfunction :fs1: Sorry but i'm "EFI STUPID" . . . Mike

Jeez, I don't know . . . I had put a 350TBI into my GTA it had a bad O2 engine ran fine just popped on the SES light and got 15mpg instead of 18mpg . . . This thing simply won't accelerate then idles rough . . . But you could be right its on the list of parts . . . Say dose this neat & interesting system had a main computer unit ? If so could this be malfunctioning ? Mike

I went a spending spree, i about bankrupted myself . . . only 3 things left to change . . . 1. O2 Senser. 2. Fuel pressure regulator. 3. Fuel injector. Ignition module brand new made no effect only caused it to act quicker, TPS brand new made no difference again made it act up quicker . . . Ever new part makes it less & less drivable most would see that as a bad thing, i am viewing it as a good thing, it means the bad part is eventually going to completely fail make it much easier to find ;) So i'll be ordering up: O2 sender, Injector and fuel pressure reg . . . after that i have no idea what else could be bad ? gas tank ? the fuel itself ? filter again ? Mike

:D No :bowdown: Emissions testing here ;) yet anywho :roll: plenty of :chillin: Ban's tho :dunno: I'm not a smoker so it don't really effect me, but most my firends do so it dose effect them a great deal :hmm: Mike

2x 235/75R15C M/T's = $85 each shipped. Mike

Yup this was a pointless thread ! You guys already got me confused and pissed cause I have no idea what any of this means. Let's stay simple here. I want pull the TB off throw it in the trash can. Then drop on a carb. Then rip out the dist n toss that away. Then drop in vac dist. Set the timing. Rip out the fuel pump wires. Remove the plate install the mech pump. run a line tank to pump. Run line from pump to carb. Prime and drive. If it is not that simple it is then beyond my comprehension and won't be done. Mike

Trouble is i am running out money, i wish some body had a scanner that would simply plug into it and tell you whats going on, But nobody seems too . . . How did AMC service these things then ? Ok i have read through this post again and again it make no sense to me WHAT IS WRONG WITH MY TRUCK ? ! ? Mike

Ok maybe i'm missing some thing but the 350TBI truck engine i had i simply swapped out the intake with a jeg's intake set a carburetor on it and dropped an HEI dist ran power to it ans shazzam it ran . . . Mike

I guess i'm not getting what your saying about needing a way to control the spark ? I have had many V-8's & V-6's with HEI and Breaker point ignitions and to my knowledge they didn't have comp ? . . . Mike
