Re: 95 grand cherokee
You posted in the WK section, you have maybe more change on response at the ZJ section.
Besides that, i would have a look at the cable loom which runs around the back of the cylinder head. It can be rubbing on a stud and wear the isolation away, causing a shorted wire. The short mostly happens under torque, when the engine tilts a bit and the wire moves against the stud.
