rough idling and acceleration

Jan 11, 2004 5 Replies

i have a silverado pickup, it starts good and quick, but is rough on idling,,,the worst is acceleration, it jumps and sputters, and mainly bad running. i have replaced the pcv valve, i had someone do a tune-up about a year ago, i have also replaced the fuel pump, the injectors seem to work fine,,,to me. I looked inside the distributor cap the other day, and noticed some corrosion on the distibutor cam and inside the cap...could this be a problem..like duh? I just hate to spend money on unnecessary parts. thanks

The year, engine type, and mileage would be a HUGE help.
