Hello, I guess to start things off, I had just replaced the transmission on my 96 dodge avenger es, at 158000 miles. Car ran fine with no problems for 2 full days after tranny eplacement. I went about 15 miles to take car of something and on the way back I figured I would fill her up. Well for 10 more miles it still run smooth. I slowed down to make a turn in my driveway and it started to stall, missin like crazy. So I went to the parts store and got some new plugs, wires, cap, and rotor. Figuring it set for so long it could of used it anyways. So that didnt change anything. I then changed the fuel filter and put some dry gas in the tank figureing it had to be water in my tank. Well that didnt change anything either. Since doing this I have prolly out 30 gallons total in the tank and nothing changed. Well I had a map sensor code so I replaced it and I also replaced the TPS. Still nothing changed and still had map sensor code. So I thaught PCM or wiring issue. Look at wiring closely and got a different PCM. Well guess what. Nothing changed. So I got a can of sea foam and some new plugs and replaced the plugs and cleaned the intake all up really good. Also while I had it all apart I changed the gaskets for the upper and lower plenum. Well I atleast idols fine with hardly and miss or anything. I can drive it but it misses much more the hotter it gets. First startup I can drive it almost like nothings wrong. Anyways under medium to hard acceleration it misses like crazy. Anything over 3K rpm theres not hesitation and no miss as far as I can tell with that rpm anyways. Fuel injectors are fine and work correctly. If I start the car and floor it it sits at 1500 rpms just bogging away and will not jump up till I release the pedal. Could this be a fuel pump or a distributor problem. I have been told dis. But its 500+ dollars and I want a opinion from a pro. So thank you very much if you could help me out with this. Oh yea the only code I get now is 43 with the key on key off trick, which is mutiple cylinder misfire. Well I hope to here from someone soon. Thank you.
