my CEL light has returned. someone posted and said to use fuel injector cleaner. i did and it worked for about a month. the light is back and i dont think that i can use the cleaner again. it says not to use it that often.

go to a autozone and they will pull your engine codes for free and take the code nuber they give u and post it on here and someone will tell u what that code means thats what i did and it turned out to be an O2 sensor
