History: 2008 with 111,000 miles. I started getting skip or stutter only occassionally and put a low end code reader (Actron Pocket scan CP9125 with only read/erase function) and it gave me P0341 = camshaft position sensor. Replaced the intake one first (got it off ebay for $109 wanted to make sure it was identical to OEM, it was) and was good for about 75 miles. Replaced the exhaust as well and it happened again. This time I got P0336 p/d (crankshaft position sensor, the pd apparently means pending) and the engine stalled and was hesitant to run, but I was able to get it home - about 5 miles. I never got an engine light. Because of where that is, I took it to an independent shop and they contacted a friend who is a certified LR mechanic. He had never seen one in the shop for that problem. They didn't want to rob me and I took the car back. About 15 miles later, it happened again.
Now the scanner has no codes, but it does show "MISFIRE FUEL COMP CATALYST EVAP 02 SENSOR O2 HTR". It stalled after I got that message. Still no engine light and no codes.
Any help out there?
Thanks for taking the time to read. I hope I was fairly clear.

 

Check for leaking/disconnected vacuum connections which typically show up as O2 sensor malfunctions.

 

Interesting, thanks. I would think if that were the problem, it would be a more consistent problem and it only happens intermittently once it is warmed up. Also, I discovered the messages I listed in caps, are codes that require set number of cycles to issue a code fault.
I will look at hoses though. Thanks
