Heyo! I keep getting this code p0102. It does not turn the check engine light on but it is always stored in the system. I noticed sometimes when I stomp on it, it hesitates. Also it rolls coal pretty good (not sure if that is normal with my tune) I have cleaned the maf and map sensors with no change. The previous owner has removed the def system and it is tuned (not sure which tune it is running). Has anyone experienced this code before?
