Engine Performance problem
2002 Chevy Impala 6 cyl Two Wheel Drive Automatic 80000 miles

Problems started with hard starting mostly when the car was warm. It would not start warm with no accelerator pedal. A small depression of the accelerator pedal and it would usually start. I still have that problem but now the car will occasionally stall when turning a corner or coming to a stop. As a test, in nuetral, if I tap the accelerator pedal a number of times, I can occasionally see that engine RPMs drop and the engine will almost stall. A ECM scan throws codes. I am overdue for a fuel filter replacement. Where do you suggest that I start troubleshooting?

Do your fuel filter and then start with the idle air control valve. A good throttle body cleaning and then let me know how that goes, you said its throwing codes? Or its not throwing codes, if it is, what codes are they?
