check your MAF sensor, Air Filter, gas cap.

9 times out of 10 thats what causes a CEL.

That just means that they didn't do anything, and just reset your ECU.

That is funny and true. Once that happened to me after racing and I cleaned the MAF and reset the ECU...all gone. Better than the girl I knew that bought a certified Camry and they tried to charge her almost $500 to fix the charcoal canister for a similar CEL. Glad everything worked out.

For my own clarification and future reference, how do I reset the ECU? Is it as simple as unplugging the cable on the negative end of the battery and plugging back in?

to reset the ECU, remove the negative terminal for 6-7 minutes.

this thread has got my thinking...got another question:

whenever I do a mod, i.e. adding CAI, pulleys, or headers, do I need to reset the ECU every time?
