I have a 1992 Park Ave and while on my way to work today The car was running normal temp (below a 1/4) and it was like it died, but didn't and I could floor it and nothing like 2,000 rpm's. I put the tranny into Neutral and same would only rev up to about 2,000 or 2,500 rpm's. Now I have been having previous problems with the car not starting after warm until completely cooled down. I did the IGN Module, cam sensor, could it be the Catalytic converter. It seems to me that the exhaust was almost not able to flow out properly. And this is a 3800 Non-supercharged. Anyone help!?!?!? Thanks (josh)

 

Could be a number of things, but my first guess would be fuel pump. You might be wise to pay for a diagnosis. If it is the fuel pump, you probably want to have it done despite the expense, because it's a tough job.
