Have a buddy with a sweet jeep, says he's got a CEL with a P1698....with a cheap scanner, there is no detailed description and I'm a FORD guy lol. He says it will stumble and die...cycle the key and run like a top for a while and continue the same process...any jeep dudes out there???

This is usually due to an internal problem with the PCM or a wiring problem to the PCM causing a loss of signal. Has he been wheeling anywhere that he could have gotten some water at the PCM?

No...street machine, no water...but that narrows it down...thanks!

Automatic?

Automatic?

yes

Could be a lost signal to the TCM, but it would likely have shifting issues
