I have a 98 pontiac bonneville se with 150K miles that will idle fine but bog down when trying to accellerate. After running a diagnostic I was able to eliminate all trouble codes by replacing the o2 sensor, the tps and the maf sensor with the exeption of system lean. Do I need to replace the fuel pump, the car does this at 4000 rpm, every time.
have the same problem?
