It sounds like your Fuel pressure regulator is going bad. Check the vacum line to the regulator. A dirty fuel filter will do the samething but hope it's not the Injection system. Good luck

Two symptoms here Keith, and I just had this, same car year and model. The pedal could either be a bit loose, check the cable and throtle. Have someone check, when the cars in neutral,they manually rev it, and watch the RPM's. They should go 3-4 as normal. If this is the case, and its not the cable or pedal, REPLACE spark plug cables and wires. Odd, but that was the fix to mine. Hope it helps.
