forgot this one

after 500 miles my check engine soon light went on.. it freaked me out cus last time it turned on it was the mass airflow sensor.. so it stay on and like 50 miles later it turns off. then again it turns on and 50 or more miles it goes off...and tonight it was on again then off at 20 miles? i know if you scan it it tells you whats wrong but what can it be if it goes on and off like that? something small?

Do you have a cat on it? Maybe a sign cat is becoming pluged. Causeing it to intermitently throw an 02 sensor code.

no my car is stock. did change the mass airflow sensor. should i take it back to the shop and ask her if the MAF is working prop? i did replace the clutch.. but the light wont be on for that right?

Umm if your car is stock it most likely has a cat on it....What's the mileage?

Could be a lot of things. I had a problem with my air pump, it would turn on the light randomly. Have it scanned and see what comes up.
