FIRST POST SO FORGIVE ME
Driving back from bristol yesterday, not pulling. (THANK GOD)Went to get on interstate accelerating foot half to 3/4 on throtle, truck made a blow back type noise under the hood power droped for a split second came back up and then did it again. I have scangauge II no codes shown. Did it the rest of the way home, 230 miles. Accelerate, turbo spooles up, hickup.
Thought I would ask the biggest knowledge base I know of.
THANK YOU
Wouldn't hurt to check your fuel pressure...both at idle full throttle to confirm your not starving for fuel. Not likely, but one thing effects another on these engines. Forgive me because I don't own a ScanGauge...but I think you have to may have to program the "X values" for it to check for all codes.
