Ok I'm at wits end here and need some advice.
I have a 2012 Ram 1500 Bighorn Crew 4x4 with a 5.7 hemi. The truck is stone stock with exception to a set of BBK shorty headers that were installed due to a craked manifold.
Anyway, over the last few monts the truck has developed a bad dead spot when accelerating. Sometimes it is normal and other times it doesnt matter how much I push the pedal it just doesn't accelerate, then BAM!It hits hard and the truck revs hard and accelerates hard. There are no trouble codes and the teuck starts and idles great. I've installed all 4 O2 sensors, IAT and MAP sensor along with 16 new plugs, removed the throttle body and vleaned it along with the upper cylinder cleaning. I also have doe the recalibration of the throttle with key in the on position and depressed and release slowy thing.
Im out of ideas, anyone out here have something to offer...
