Default dodge ram 5.7 hemi
Hello everybody, am new here. Need some help I just bought a 2005 dodge ram 1500 hemi. I have the same p0300 problem doing the fuel treatment seeing some progress. One question is it normal that my RPM doesn't go over 4000 when in park?

Ram Year: 2011
Engine: Hemi 5.7
Default P0305 misfire
Recently I purchased a 2011 Ram 5.7 with 92,000 miles on it and after about two months, got CEL, shaking and loss of power over 3000 rpm. Dealership replaced spark plugs, de-carboned engine, cleaned throttle body and injectors and checked the coil packs. $650 later I was driving down the freeway and same problems occurred; right back to dealership. This time diagnosis was bad cam/ lifters and valves. Fortunately, I had purchased an extended warranty that covered internal engine parts in order to finance a high mileage vehicle. Long story short; dealership still has vehicle ( waiting on back ordered lifters) and reassembly for 4 weeks! At least it will be covered.

Is anyone monitoring this thread? I could use some help with a misfire code as the title reads.
