Pontiac Problems? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Can you tell me if the check engine light is coming on an how many miles are on the vehicle.
Thank you. A surge that does turn on the check engine light on this vehicle is typically caused by worn spark plugs or a dirty mass air flow sensor. I would recommend cleaning the sensor first to see if that helps. Is this something you plan on doing yourself?
Then the mas air flow sensor needs to be cleaned and the signal checked. Besides this sensor the issue may be in the transmission.
Please let me know what he finds or if you need more help.
