2004 ram hemi Well have gotten a P0442 an P0455 last couple days I know its something to to with evap system haven't checked yet ,,then yesterday had been out driving truck and stopped at a friends for hour or so and started truck and had no throttle and the lighting bolt flashing,,truck would idle but no giving it fuel,,shut off restarted and was fine but it threw P0442 P0551 P0340 unsure how they all relate to each other ,,cleared them and its still running normal and it has a new cam an crankshaft position sensors already replaced ,,would a power steering pressure switch cause the the no throttle an the P0340 codes ?
The previous owner said it would stall on long drives but always restart but I don't know if he was getting these codes or if the stalling he experienced is what happened to me this time ,,any comments would be appreciated of related issues
