trouble accelerating

[scottiebigs]

After my '88 Cutlass Siera has been running for a while, it has difficulty accelerating. This is true whether I'm looking for an extra burst of speed to pass a vehicle, or if I come to a stop and try to get back up to cruising speed.
Then, when I was stuck in stop and go traffic, the car repeatedly stalled.

Any ideas what the problem is? Thanks.

Just a guess, try a tune-up.Plugs,wires,fuel filter.....

Sounds like it has something to do with your fuel line. I'd check your fuel pump and/or filter. Good luck!

I've addressed all those things. In fact, the fuel pump was changed a few months before the problem developed. At first, a mechanic thought the problem was because the coil pack wasn't firing so I replaced that. It worked for a few days then the problem developed again. I've found other postings in here that generally tie the symptoms -- loss of acceleration, stalling -- to the coil pack not firing because of the crankshaft position sensor. Hopefully that that is the root of the problem, and can be easily fixed.
