AMC-MJ

:cheers: Keeping fix it :fs1: yep it sucks keep fixing it once its finally fixed it'll run better then before it broke :bowdown: Mike

Quick thought just popped in to my head :wall:, what if some thing cause a momentary clinch in the system ? Say a wire with abre spot is floating around catches some thing shorts for just a split second would that cause it to malfunction or misreading until reset by shutting if off and restarting it ? or A leaking vacuum line is leaking but it run able till some thing drips into the leak causing a momentary misreading or malfunction until reset by shutting if off and restarting it ? Or Am i way off on this a momentary thing would cause a stumble then it would automatically recover ? Mike

I'm confused now, changed the Map sensor, and it combined the 2 problems ! Now I have steady smooth idle and good throttle all the way to wide open. Then It Randumly jumps in a rough choppy idle where it won't accelerate. But I'm also on the RED square of the gas gauge. Now food for thougt when it acts up now ? I can shut the key off while idling or driving restart the truck and it runs perfect again ? I now have the battery disconnected to give that another try . . . Then its off to get gas . . . Ill report back ! Just think about the above info truck acts up shut key off restart truck runs good for a while then repeats the cycle . Mike

any body have a Vacuum diagram they could post up ? . . . Mike

Soon as i can get a ride the parts house i'll be snatching up a MAP sensor after that i am blaming the Computer 150% and i'll be blaming the vac system 50% leaving me 200% pissed off :fs1: :dunno: AMC-V8 :dunno: Nice 2bbl Carburator :dunno: 5spd manual transmission :dunno: I must love this truck or I really hate myself one of the 2 . . . Mike

Looks as tho, the D35 is not as bad as most say it is . . . it's a coin toss axle i'm guessing some last forever other blow up and or come apart continually . . . I must be one of the lucky guys i have an Awesome D35 and a junk truck :fs1: Mike

I called my old boss: Me-"what ya got going this summer would want my help i got had" old boss-"Grass ain't always greener ya know" Me- "I know and i knew" Old boss - " it took 3 guys to replace you i can't just fire them to hire you back tho i want to" Me - "if ya got enough work to add me then keep me in mind but do NOT fire guys to ReHire me" Old boss"Ok i got some bids in i'll let ya know if i have anything for ya" I did the walk of shame like a big boy :'( - ;) hope it pays off . . . Mike

Ok hooked the battery back up, No such luck ran all rich and rough took it for a drive brought it back, my roomie and best friend of 20 years . .wow 20 years . . .anywho he said he a few blocks it ot stalled out now its back to idling perfectly and stumbling on acceleration but i limped it to work at rolling 3-5mph ;) Now he has seen both sides of it acting up the not idle smokey drives and the good idle no smoke non drive :cheers: . . . So what ever is bad the truck keeps flipping back & forth between the 2 symptoms . . . I wish i could get a meter on it when its doing the original symptom see if its reading .100V see if its going from one extreme to the other way to rich to way to lean . . . Mike

I do land scape & lawn care so, I was actually coming into my season . . . Winter is lay off season for me unemployment and plowing going into work when it snows . . . Thats the crappy part about it ! Mike

Battery cables are unhooked i'll hook them up in the AM and see what happens . . . It's annoying but it is at least drivable some what now as where it was undrivable before . . . Might just be time for a new Computer or a Carburated AMC-V8 :eek: It's my only usable set of wheels right i'm down as long as its down . . . Mike

The new unit reads the .920V then fades back to the .840V, the old unit reads 0.00 - 0.00 V . . . Mike

Up, both of them cause it puke black smoke ! The new one allows it to idle the old one let's it die out at idle ! Mike

Its steady .920 at idle as the engine rpms increase the number slowly drops to .840 where it quits falling ! Mike

One wire steady 13.9V Second wire 0.84 reved up-0.92 idle Third wire steady 0.00V OHMs sensor side not running : New unit A to B 0 ohms B to C 0 ohms Old unit A to B 13.87 ohms B to C 0 ohms Mike

I been using a bare spot on the radiator support as my grounding point ? Bad idea ? Mike

One wire reads 13.9V Second wire reads 0.00v Third wire reads 0.90V The auto parts store said they could have another one of the same unit in a couple days but if it dose the same thing he said some is causing it to do what its doing. Mike

Runs the exactly the same ! Testing voltage now ! Mike

Standard is what the box says I was its the same brand it from the factory I'm told ? Its non returnable so I'm out 60 bucks either way ! Mike

Well smart @ZZ ! It was 60 fricken dollars ! SG-20 is the part number ! ? Mike

Changed out the O2 now its puffs black smoke faintly it idle then pours black smoke ! when your on the throttle accelerating . . . So it managed to fix the stumbling bumbling studdering none accelerating truck now i have a smokey barley idling some time stalling when ya let off the throttle truck that accelerates like a rocket ship ! . . . I bet it went from 20mpg down to like 8-12mpg judging by all the black smoke . . . annoying but drivable . . . Now what to check ? what to test ? what to replace ? Mike

Well, in lou of becoming Jobless in about a month i decided to call and call and i finally found some body with an O2 Sensor in stock ya its $10 more money but i have it now . . . I need the old jeep to pull out of its little gloomy gus moody situation and and run hard i gotta find some work before I'm out of work . . . Mike

Yea i guess i gotta feel some what lucky, they gave about a months notice . . . Mike

I got informed Friday that by April 4th they will no longer be needing at work WONDERFUL ! They said it was year round gig, after snow removal is over they got other guys coming back good old bait and switch to me . . . At least i got a month's notice i guess, i got 3 city app's ready to be sent in monday morning . . . Mike

Well if the D35 Rear end fails then ill simply replace it with a nice AMC-20 ! Mike

:cheers: The D35 is perfectly fine axle :cheers: Mike
