97' OLD'S CUTLASS SUPREME (TURN
Beware...some GM cars , especially 94-96 were made with two flashers in them. One was for the emergency flashers and the other was for the directional. If you flashers are located under the dash by the steering wheel look around you will see the other one. Be sure to replace it with the proper one.

Misfire when accelerating
Year, make and model of your vehicle would help. If you can check for codes in the engine control module, it would also help in better diagnosing your possible issue and resolve.
What have you done so far as to diagnosis ? Have you checked for any vacuum leaks ? Have you checked if your coils/plugs are in good condition ? Adding as much detail information is best.

Car accelerates by itself; idles way too fast
Focus on the P1635. The pcm is not providing a valid reference voltage to the sensors. Therefore, the sensors are unable to provide feedback to the pcm. This problem can be the pcm itself or a short somewhere on the wire that is supplying the reference voltage. I would unplug the sensors and then check to see if the reference voltage comes up to spec (5vdc). If it doesn't, trace the wires looking for a short to ground. No short--replace pcm. If you find a short, repair. If the voltage meets spec with the sensors unplugged, plug them bacl one at a time checking the voltage after each one is plugged back in until the voltage drops. When it drops, you have found the sensor that is the source of the short. Am I making sense? Then put your old tps back on.
