Engine Performance problem
2004 Chevy Impala 6 cyl Front Wheel Drive Automatic 85,000 miles
I have a 2004 Impala SS-Supercharged engine. As I was driving one night, the engine stalled and quit. I towed the car home and assumed the fuel pump was faulty. I replaced and the car started but ran only a few minutes and died. I replaced the fuel pressure regulator and filter. Fuel is present at the fuel rail/injectors. Still will not run. I disconnected a plug wire to check for fire; spark is present. With the wire disconnected, the car began to run again, rough idle, and died.
I pulled the diagnostic codes and they are: P0101 and P0452. Mil codes: Inc, Comp, and EGR.
have the same problem?
