A friend of mine has been trying to wheel with us and has been plagued by a gremlin. His 06 4.0L TJR automatic does not like to climb obstacles while on a trail. It will sputter and/or die, resulting in a no-start or long crank and often setting a CEL. Codes that come up are for the MAP sensor, Camshaft sensor and one of the O2's. On the road, flat trails, or declines, it works absolutely fine. Since the onset of the battle, he's replaced the fuel pump, OPDA with Mopar & aftermarke CPS's and it continues to do the same. The only time he can get it to repeat is while on the trail.
I looked at the wiring schematic and all 3 sensors have a different signal wire but share the same ground. I plan on testing the ground but has anyone stumbled across a similar issue and resolved it to something different?
