Leading up to this I had no obvious signs, and wheeled last weekend without issue (thankfully).
I am getting intermittent stalling that I just can't figure out and haven't gotten a consistent CEL (I believe one was a red herring - a misdirection, which we will get to in a minute).
So far (with tests between each change that included parts)
* First Stall
* P0457 - replaced my OEM locking gas cap with an OEM non locking
* More stalls
* Replaced the Crank and Cam sensors (both were replaced last fall with the same issue... I had them in the bin in-case the others weren't MOPAR (these were originally done by a shop last year)
* More stalls
* Replaced all 4 O2 sensors (crossed my mind since a month ago I got a few O2 warnings)
* Cleaned the Throttle Body (idled with light sprays in the body and IAC)
* drove great all Thurs, idle felt smooth - one stall
* Friday I run out to get to the tire shop (I’m supposed to get 33s this week), stalled out on the way. This time when I started up after removing the key it would sometimes start and just sputter out. After a while of trying this I got the P0038 family of codes (typically meaning the cat system). However I’m not convinced of that given the dozen restart attempts immediately proceeding.
* Traced all wiring to look for shorts
* Checked all the grounds I can find
* Unplugged and re-plugged most connectors
* Blew into the EVAP line to check for clogs (at the solenoid in the bay on the cruise control bracket)
* Switched around relays to check for them going bad
* Checked all the fuses in the cab and engine bay
My last thought is maybe the fuel sending unit - however since it's an intermittent failure the pressures hold fine.
I’d rather know what’s wrong than keep guessing and tossing money at it but I’m not getting any new codes as I keep trying to drive it.
I do have a few parts in bound for the shelf in case they go out of availability and for planned work this fall (TPS, new Bosch Fuel Pump, Autolite Iridium Plugs).
What else should I look at? What else can cause the engine to just shut off?
