engine falls on it's face at half throttle, backfires up the front Hey guys I have a 6.0 out of an 05 2500 with the 4l80. The truck ran great at first. I am now having problems where the engine falls on it's face at anything over 2500 rpm or if you stab the throttle. It will back fire or pop up the intake as well.
I am getting no codes what so ever. My pedal reads 7% at idle and seems to move in a linear fashion however the last 1/3 of pedal travel is useless.
I am stumped, please help.
