went for short trip saturday morning and 3/4 mile from house jeep stalled. it would roll and start in neutral, eventualy had to stop place in park and restart. up to this point we had intermittent engine stall but not like this. no "check engine" lights till now.. just had code scanned..

P1391

CMP/ CKP intermittent signal..

do I replace sensor , or is it timing chain or something else??


just bought this thing 3 weeks or so ago..

thank you
