Sounds like you have an auto? If so thats your problem, could be as small as not having enough atf, and could be as bad as signs of a premature death...
if you have a stick, i dunno, maybe a slipping clutch bad cat or something

hrmmm, could be a failing maf/tps/02 sensor, which would be easily revealed by pulling the codes, the codes stay stored even after the cel goes away.
get that read first...

did you have your CEL read? usually when you have a light come on and then go off it's a sign of a misfire. Misfires are usually caused by fouled spark-plugs and bad spark plug wires. Check those out. It would cause both problems. You can see if your spark wires are arcing to the engine by taking the spark cover off and looking at it at night when it's running. Check to see if you see any light where light shouldn't be.
