Alright so I have noticed lately that my engine is throwing a check engine light when I roll from a stop. I have a gsr with an injen intake, dp back exhaust, and a aftermarket bov. I use a cobb accessport for tuning and am running the required map for my mods.. Injen Stage 2 91 octane map, ohh and I have my boost pill removed. It is soo weird because it does not put the check engine in history so i cannot see it on my accessport to find out what it is. It dings and shows the check engine light then it is like it erases it right away. Anyone have any ideas?
