Damn jeep is throwing codes!!
 
On my way home tonight my jeep almost stalled and misfired . I ran the codes and came up with :

P300-random cylinder misfire
P335-crankshaft position circut
P339-crankshaft position circut intermittent


any ideas? Bad Crankshaft position sensor?

Tried clearing the codes but it came right back along with some nasty bucking and hesitation . Got it home and the thing took multiple times to start. I had a extra crank sensor on another 5.7 motor and swapped it over and cleared the codes. Everything seems fine now . I like how there is a hole in the engine skid plate so u can change the sensor

Crank sensor. $40something quick fix.

1 bolt, 1 plug, that's it.

Yep. I had to replace mine. I couldn't get over 10 mph without bucking/surging.

You've tried everything else. It wouldn't hurt to try the cam and crank sensors.
