Check engine light comes on from time to time.
Service engine light comes on sometimes for a while and then turns off. I had the truck serviced and determined the mass air flow sensor was having problems. I had the sensor cleaned and the problem ceased for a while. Now the light comes on for about a day at a time. It only comes on when you give the truck a lot of gas. (like when accelerating hard to enter the interstate) When the light comes on the air in the cab can smell like fowl burning oil. Is this as simple as just replacing the sensor? Or is there more involved?
First step - have the check engine light or stored fault codes scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply with the specific fault code as 'add answer' for more assistance.
