The problem your having sounds like the ecm is running the car in safe mode. I would initially think it to be a knock sensor problem. The scan tool your using is the wrong one too. OBD II didn,t start till 96 model year. You need an OBD I scanner. Get that scanner and see what it says. You can probably just use a paper clip or something of that nature to put in two terminals of the diagnostics port. If you have a manual, it should tell you which two. turn your ignition on and count the flashes of the check engine light and look it up for the code. the book will tell you exactly. good luck
