scan codes again and post codes so we can adv. could be o2 or fuel trim issues depending on code
I agree with greg
THE CODE IS PO171
code is showing lean bank 1 could be vaccum leak on that side or plugged inj or a number of other issues. exhaust leak on that side seek help
It is going in the chevey garage wednesday the scan at auto zone said it could be oxygen sensor ignition fire repair or fuel injector problem there was 2 codes sat they thought it was the mass air flow sensor my husband replaced it they cleared the code and by evening the check engine came back on so when we took it back to auto zone the p0171 code was coming up the other code did not on his way to work the check engine light went off we still have 7000 on the warranty so we figure they will have better eguipment to find the problem
