I have had this problem for about two weeks now. I have replaced my ECTS, tested MAFS,inspected spark plugs, cleaned throttle body and used injector cleaner. My car seems to run fine while warming up but as soon as it gets to the point where it starts to get a signal from the O2 sensors it acts up. I press the gas to accelerate and it seems as if it's choking or something. Idle's fine , but burns a ton of gas. I read in a post that bad oxygen sensors wont cause stalling. THe only codes I have recieved are for oxygen sensors. Can anyone give me some insight?

 

BUMP

 

I assume you were getting codes for the ECTS? If so replaceing it was definately necessary.
If your still getting O2 codes, then you need to replace the O2 sensor.

 

fuel filter needs changing?

 

I changed the fuel filter and PCv also. Forgot to include that. It only seems to occur during the warming up
