Computer problem
1990 Pontiac Firefly Front Wheel Drive Manual 260000 miles

Hi my car is running well but when I am idling it sounds like I am pressing the accelerator and depressing it in intervals of 5 seconds approx. It does not rev at a consistent rpm but goes from an idle to sounding like I am pressing the gas. I need to do an ODB 1 test but don't know where the sensor is in the car to plug it in. It may be a sensor? Does anyone have any idea what this is?

Go to Autozone its a free public service and have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.
