Trying to get rid of the 96 but having some starting issues. Starts just fine cold and hot(first start of day and if you shut it off for under 10min) it will fire up first crank. If its sat for say 10min-5 or 6hrs it fires then dies then just cranks tiull it unfloods iself. It is dumping WAYYYY to much fuel in. I am also getting about 3mpg. zero drivability issues as well. No codes.. I did a full tune up(plugs, plug wires, cap and rotor). Took it to dodge and had them test fuel pressure, link down test, injectors, clean the inj and scan the truck. they said they did all the testing they can do and all sensors and all readings came back good. i myself tested the IAC, tps, MAP, replaced coolant temp sensor, and the 02 sensors. no change what so ever. So whats next? I also seafoamed it and ran more seafoam in the tank. Reset pcm..etc. I am at a loss as well is dodge and my old man. plenum is not blown to bad(meaning its not sucking oil and not pinging and the pan is fairly clean and has been). btw temps down sub zero at night all the way up to 20s. so cold night fires great.. and when hot it fires great, but warm is a no go..

 

Which temp sensor did you replace? The one wire? Or the two-wire??

 

Replaced the two wire(the pcm one)

 

Ok, that's the right one.... and the first thing I would suspect given your symptoms... What brand O2 sensors?

 

mopar direct from dealer. I have a cutted cat but have had that... So thats not it. im beginning to wonder if my pcm is the issue and its just stuck in a weird sayyy cold loop? and its not enough to set a CEL or throw a code?

 

That is the last link left in the chain.... if the PCM is getting good data, but it is still burning that much gas, something is seriously awry..... I would be sore tempted to get one from the junkyard, not worry about flashing it, and see if it doesn't improve things at all, if it does, THEN get it flashed.

 

why do i need it flashed if i got a 96?

 

96 is OBDII. I do believe the PCM is aware of the VIN programmed in to it, and it may get upset if they don't match with the SRS, and ABS. (and the lites will come on.....) Then again, it may be perfectly happy, and not even care.

Taste, and see.

 

haha, will have to test it out. could a bad plenum cause all this? i use literally no oil in 5000miles running 0-20w syn in the winter and 5-30 syn in the summer(yea i said 0-20w... it gets cold here)

 

From the Mopar catalogue. 1998 and later models require Vehicle Identification Number (VIN) and Mileage encoding by a Chrysler franchised dealer. So your good to go.
