Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is***** for the question. Can you tell me if the check engine light is coming on when this occurs? Does it occur primarily on take off?
Sorry for the delay in my response. I was unavailable earlier. It sounds to me like the mass air flow sensor is not reading correctly. Have you had the computer scanned for codes when the check engine light is on?
That is what it sounds like, but being that you had O2 sensor codes it can be low fuel pressure or a fuel filter issue. What I would do it clean out the MAF. If you remove it you can spray it out with MAF cleaner. See if that helps.
Try cleaning it first as that may solve it.
