Engine Performance problem
2007 Chevy Equinox 6 cyl Two Wheel Drive Automatic 35000 miles
The past few weeks my check engine light has been coming on and then going off. I have also noticed a problem with acceleration when the engine first gets going in the morning. It is almost as if when I push the gas it has to think for a minute before going forward. It kind of jerks. As I continue driving it stops. I took it to the dealer and they had me clean the fuel system.
It worked great until today. I just filled it up a couple of days ago and the check engine light has come on again. I tightened the gas cap, but nothing changed. Any ideas?
