Stalling Directly After Hitting A Bump

[Craig 06 TJ]

So after my last wheeling trip, I got a TPS code which quickly disappeared on the way home. But since then I've stalled 3 times in the past two days. 2/3 times the stall came directly after hitting a bump in the road. She'll start right back up though. I have noticed that the throttle body is "wet" as well as the valve cover. I get an O2 sensor code at random as well. If anyone has any idea what's causing the stalling or where I should start, please let me know! Thank you!

Check the wiring harness going around the drivers side rear of the valve cover; the harness has a tendency to rub on a head stud which causes bare wires in the harness that will short out on the stud.
Check the (3) 32 pin harness connectors are firmly snapped into the ECM receptacles and verify the pins and clips are not oxidized.
As for the dampness on top of the engine; you should determine if that is oil or what ??
