it seemed to start all of a sudden. i was slowing down for a traffic light and when i stepped on the clutch the dash lit up. i was fishing around to try and inspect everything and im 95%sure its the egr system. the truck runs fine above idle. any direction someone could point me in to attempt to fix this? i wanna take the egr off but my truck wont be exempt.
