OBD1 codes

does anybody know where i can get a list of OBD1 codes for my 94 sable. Went to autozone tonight to get the codes read bc my check engine light randomly came on last night when i started car to come home from work. It was weird bc the car has been running fine, and it ran fine to work that morning but it rained all day and when i went to start car that night the engine was sputtering, idle was jumpy and car would shut off. I reved the engine some and it enabled me to finally keep the engine running long enough to get home. I left the car in the garage for the night and when i started it up this afternoon it gave me the same problem as last night but after a couple more starts and some reving of the engine it now runs fine once again which leads me to believe maybe a moisture problem from the rain maybe dealing with some old spark plugs or something. Anyways, a point in the direction of where i can find a list of codes would be greatly appreciated.
