Im pulling my hair out on this one... Idles good. Runs good. Stalls SOMETIMES when in reverse and turning. Cleaned throttle body, New plugs and wires. Doesnt matter if its cold or been warming up for a half hour, randomly stalls, ONLY when in reverse and turning the wheel. ANY suggestions or help i would really appreciate. PS was looking into replacing PCV valve, autozone and advacned looked at me like i was a moron because their computer says a 99 cherokee 4x4 4.0 doesnt have one? EGR? CCV? PVC? TPS? also not throwing a check engine light either

 

Tilt steering loose by chance ?

 

Tilt steering isnt loose. This morning it stalled backing into my parking spot at work. After work it ran just fine, backed all the way down the driveway for the hell of it.

 

Have a look at the wiring loom that goes around the rear of the engine by the injector rail, also check wiring to the 02 sensors.....
