gearhead204 Posted September 28, 2014 Share Posted September 28, 2014 check all the above mentioned stuff also how much boost or manifold pressure are you building? a plugged charge air cooler , a plugged air cleaner, or a leak in the charge air cooler or piping will cause this. or for some reason you are over fueling. start with the simple stuff first.
