I have a 2001 and about a month after I bought it the service engine soon light came on and stays on constant. I put it on a machine and they said it was my fuel injectors. I talked to some chevy machanics and they told me to get some MAF cleaner. so I bought some of that and cleaned out the MAF that goes to the Air filter and then unplugged the battery. i plugged it back in and the light went out! Well only for a day. Do anyone have any other CHEAP Ideas to fix this?

 

we need to know the code(s) you're getting.
