I have been chasing this issue with my Talon where it has been sputtering and stalling out. Ive replaced the PTU, tried a salvage yard MAF, replaced the plugs and wires, replaced the fuel pump and fuel filter and even put in a reman ECU and I still am left with this issue.
The car runs just fine when its cold, drives just fine. Its when it warms up to operating temperature where I have this issue. If I give it any more than about 25% throttle it sputters and stutters and is very unhappy. I gave up chasing the issue and took it to storage in the fall. While driving it there I had to 2 foot it at stop lights to stay running and my friend that was following me noticed when I would accelerate it would puff black smoke. When I got to my barn it seemed to be running VERY lean, smelled hot. Went back and after it cooled down the spark plugs look like the engine was running very lean.
I'm not sure whats left here. Nobody in town really knows much about these cars and the Mitsubishi Dealer is hesitant to start digging into it when I take it out of storage in the spring.
Somehow the air/fuel seems to be off leading me to the MAF. I have a laptop with data logger software, not DSMLink, I cant recall which software it is but the ambient and coolant temperatures seem to read accurate. I tested the injectors by disabling them one at a time in the program and all the injectors seem to be functioning as intended. I'm kind of at a loss here. My Local O'Reilly can get a reman MAF for $114 plus core, should I go that route? I could also throw in a coolant temperature sensor and even a coil. It acts the same with my old ECU which when I pulled it was also a reman and the board/caps looked perfect.
Id love to get this back on the road so I can enjoy it, but right now it really cant be driven anywhere reliably. Thanks for any assistance!
The last shop I took it to had it for 2 weeks, they did the fuel pump, filter and injector cleaning, that was in August.
