Crank Position Sensor

Hello everybody I have a 1994 ZJ Grand Cherokee with a 5.2. It's had a missing issue when reaching operating temperatures. I recently replaced the thermostat but the miss is still there. Its throwing codes for the CPS so I'd like to replace it. The trouble is I believe it's located under the distributor which is tucked up into the firewall. Has anyone replaced this part before?

The part you're talking about is the easier part to plug in. It's a PITA. I had my mechanic do it and he was not happy haha.

See and that's why I like my 4.0 plenty of room to work in the engine bay. Id Luke to pick up a 5.9 at some point though.

It's really not that bad. Worst part is that one of the two bolts is in a spot that is blocked from using a socket. Gotta do the back and forth thing with an open and end wrench. Use your left hand while facing the head lights and you can reach right down there no prob. Pivot on a socket with a cpl. extensions makes the one bolt cake. Strategically placed of course.

Maybe it is the cam sensor. Ill have to check again because I forget which code it's throwing lol. Either way both are in a ***** of a spot and I'm a bigger guy so it's hard to fit in some of those tight spaces. Extensions for the win lol

A 5.9 would be nice to have. Eventually I'm gonna 4BT swap it though once the 5.2 goes
