So I have a 1994 Oldsmobile that when I get high RPMs or above 45MPH the engine will start to shake not violently but will rock back until you let go of the gas and sometimes will stall after you do so. I have replaced the spark plugs, coils, and cables and it hasn't fixed it. I have tested the compression and it looks good. I have replaced all the sensors and I got a new fuel pump and fuel filter installed and that hasn't fixed it. I think that it is the computer and it may need a new one. I have also looked at the timing chain and still cannot figure it out and thats why I came to Reddit, so hopefully someone can help because I have been working on this car for 3 months.
