For $20 you can pick up a code reader and code book. It has come in handy quit a bit for me. The code reader plugs into a plug by the gas and brake pedal basically right below your steering column. All you do is plug it in turn the ignition on and count how many times your "service engine soon" light flashes it always flashes 12 first which is the diagnostics mode code which doesnt mean any thing and after that flashes 3 times it will tart flashing service codes to you. Its really easy and the code reader is fairly cheap. Hope that helps you. Oh the code reader is in a clear box with a clear incert and its just called a GM CODE READER. The only thing is it only goes up to 1995 gm vehicles because after 1995 they swiched from a 12 pin connector to a 16 pin connector. Good luck.
That won't work on a 94. The 'flash' feature was discontinued by GM after the 93 model year. You need a scan tool to read the codes for 94 and up. Oh, you just bought a 'code reader' when you could have used a paper clip! (sorry, couldn't resist that one! )

92SSESC is on a distinguished road

I have a rough idle and the only codes I had were for excessive cycling in my AC, my knock sensor (which I have a posted a question about) and another code that I could not find a meaning for. I'll look it up and post it to see anyone knows about it. But mine idle will jump from just under 1,000 to about 1500 then go back down. Sometimes it comes dangerously close to stallling out. But it runs fine at higher speeds. I'm going to try some of the suggestions. But I have no obvious trouble codes.
