Hey guy, got a question. I am curious to see if anyone on this site can help me with this problem. I have a '98 Olds Acheiva (3100) with performance problems.
Basically... I have intermittent misfiring. Replacing the fuel filter nearly doubled my engine performance. that was a couple of moths ago, now I have only slightly better performance.
When I say intermittent, that is exactly what I mean, it will cough and sputter ever so slightly anywhere between point A and point B and never the same time or place twice.
Maintenance:
I change oil every 4000 miles
Often use injector cleaner (doesnt help)
changed plugs and wires recently (no improvement)
I know the '97 Olds Acheiva had several electrical problems. My car, however, appears to have none of these.
Somebody please help give me some ideas to try. I have been experiencing this problem for over 3 years, no ones suggestions have helped at all. The fuel filter was my idea and so far its the only thing that has improved anything.
And that doesn't help me because I have no idea what I am doing! Please help!
