2008 lgt p0103

Recommended Posts

Hey guys! I could really use some help with this if any of you have any insight. I just pulled my leggy out of storage and keeps throwing this code, P0103 (mass or volume air flow circuit high input) whenever I give it full throttle. I am assuming that it is over boosting, and I am also assuming that it is doing so because its about 20 outside and the car isn't tuned to perform at these temperatures. The weird thing is, its also stalling every time I put the car into neutral. It didn't start doing that until after l I cleared the code with my accessport. Would that be related? Has anyone had anything similar happen to them before?

Have you cleaned the MAF sensor? DO that and try again.


Use a can of MAF cleaner. Give the sensor a short blast and let it dry for a few minutes.
