I'm brand new to this forum as a member but have read many posts on this topic...but still can't get the problem figured out.
History...2002 Grand Cherokee 4.0L with 201,000 miles. Recently she's been intermittenly stumbling and after it warms up will stall out without warning. Mine, unlike others that I have read about will start right back up. It doesn't do this on every (cycle) or start but does it at least every other start. I did the key switch code retrive thing and now an getting the P0340 code which I think is the camshaft sensor.
I've replaced in the last 2 weeks:
camshaft sensor
crankshft position sensor
throttle position sensor
battery terminals cleaned and battery checked out good.
6 new APP985 plugs installed.
It's still acting up??
Now, I didn't use OEM Mopar parts..could I have got a bad sensor?
I've heard guys say replacing the PCM is a fix?
Any advice would be great!

 

I tried a Mopar cam position sensor..looks like the exact same part, but the new one didn't change anything, it still stalled on me. Should I try a Mopar crank sensor...new PCM? Any advice.would be greatly appreciated.

 

Stop throwing parts at it and read this. http://www.obd-codes.com/p0340
