Question about 1999 Saturn SL
One of 4 things. Your TPS [throttle positioning sensor] IAC [ idle air sensor ] vacuum leak, or intake manifold gasket getting bad.Easy test for you to do before you get into replacing parts is as follows. Start car, and take some engine cleaner spray, and spray directly onto the gasket where the intake manifold bolts onto the block. Spray liberally. If you hear the engine RPM'S change in ANY way, your gasket is bad. These cars are well known for this. I suggest that you try this first and get back to me. If this is not it, I can walk you through the next easy tests. Let me know, but if I were a gambling man, I'd gamble on it being the intake gasket. $40, and 2 hours to do it yourself. I also made a video while I was doing my own. Let me know if this info is helpful

SOURCE: How do i reset the
Depending on what state you are in, parts stores are not legally allowed to clear codes, only read them. Most of the time if you disconnect the battery for a few minutes, than reconnect it will clear the memory, however the light will come back on if there is an actual problem.
