2001 WJ - Periodic Stalling

Recently purchased a 2001 Grand Cherokee with the 4.0

I have been having periodic episodes of it just stalling upon coming to a stop, otherwise it runs strong with no hesitation.

In addition to the occassional stall, i noticed the idle would sometimes flucuate as well.

Im thinking it's a bad Crankshaft Position Sensor? There are no fault codes coming up, and I have no check engine light coming on.

Anybody have any input?

Is the CPS easy to replace, and where is it located?
