CAR STARTS BUT WONT ACCELERATE AT ALL. IDLES GREAT
1992 Pontiac Bonneville • 280,000 miles
I have been having small problems with this car for a while. Just recently I was having a driving problem it would stutter and die at 2000 rpm intermittently my first thought and diagnosis was a faulty maf with this repaired the car ran great for about a month then it wouldnt go over idle with out stalling out my fuel pressure was a little strange so I replaced my fuel pressure regulator but that wasnt the problem, it was sitting for two months so I decided to clean out the intake with some seafoam nopw it goes a bove idle but not above 2- 2.5 grand and it backfires intermittently I am down to thinking either severely clogged fuel lines or my coils or icm is bad please help the only testequipment I have is a dmm

What about a clogged exhaust have you checked the exhaust back pressure yet?Also have you checked for codes?
Oh also the fuel filter is 2 months old fuel pump is 2 yrs old so r the battery cables spark plugs show no signs of oil or misfire or over heat. One of the coils was replaced when it died about two years ago oxygen sensor is about 7-8 months old
Have you checked fuel pressure also have you thought about maybe water in the fuel etc?Any codes in the computer?
I checked the fuel pressure before I replaced the fpr thats why it got replaced fuel pressure didnt jump at all when a vacuum line was removed. Only code was from my misadjusted tps that has been fixed. I dont have a way to check backpressure but the donut in the exhaust was just replaced 3-04 months ago because it was leaking visibly, the rest of my exhaust tubes are welded and have no cracks or holes(smoke test performed)
You could have a plugged cat unbolt the cat from the exhaust pipe and see if the engine revs up.
Drop the pipe at the manifold start it and see if it revs up right?That will take the cat and exhaust out of play. Then atleast you can rule that out.
The exhaust is coming in to the cabin .It comes and it goes.One of my machanic tried back pressuring it but he did not see any leaks in the exhaust pipes.I thought was the oil leaking ...
