2011 Ram 1500 5.7 w/ misfire P0301 and low oil pressure
My 2011 Ram 1500 5.7 Hemi while pulling
travel trailer all of a sudden threw a check
engine light. The light blinked for a little bit
then went solid. The code is P0301 misfire on
cylinder 1. The misfire is intermittent with the
code going active and stored based on
whether or not the engine is under load. Oil
pressure drops to 17 at idle. I changed the
plugs and ignition coil for the cylinder.
Problems still exist. The truck runs ok until I
get on it any at all.
