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?

The check.engine light doescomer on intermittently
Customer reply replied 2 years ago
The car bucks and spits and sputters while driving mostly. In idle it does it a little.
Customer reply replied 2 years ago
I am still waiting for a response to my question regarding my vehicle. I have paid the full amount, and have not yet received an answer. The catylitic converter and resonater tested good. All.plugs and wires are good. I can't get over 30mph with my foot to the floor. Rpms will jump, and I will.get a short surge of acceleration, and then I lose it. I've been charged, and now I would appreciate a response. Thank you.
Chevy Mechanic: BOBBYSS, Master Technician replied 2 years ago

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?

Customer reply replied 2 years ago
The car is throwing a code for the O2 sensor. That's why I thought it was the cat converter, but it's not. Found out a motor mount is broken last night when I picked it up from Cole muffler tho. I'm usually pretty good w vehicles, but I'm on to my third local shop aside from contacting you for help. So could be the MAF intake?
Chevy Mechanic: BOBBYSS, Master Technician replied 2 years ago

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.

Just had a third mechanic replace the fuel filter and this still did not resolve the issue. Will look into the MAF to see if this is the cause. Getting frustrated.
Chevy Mechanic: BOBBYSS, Master Technician replied 2 years ago

Try cleaning it first as that may solve it.
