    4.7L PowerTech V8 Specific Topics
    I have a 2012 4.7l that came up with the P0300 code. I cleared the code with my gauge tuner and it went away. After driving for about a day it came back and the check engine light came back on. I changed the spark plugs and reset the code and it stayed away for a little while but came back on...

    so it finally happened. got a p0300, p0302 and p0307. before the light came on, it sputtered going up a slight incline and I thought I heard a corresponding knock. my first reaction was to tell my wife to shut it down and pull over, but it quit as soon as the road leveled out and the engine was...

    LD RAM - General Discussion
    Hey guys, here goes my first question, brand new to the forum even though I've been reading it all the time. Today I found my radiator had nearly nothing in it which was causing overheating while stopped in traffic idling. Filled it up again with water because I'm flushing tomorrow and bled the...
  6. missfire with no clues

    2011 Dodge Ram Forum
    I have a 2011 dodge ram 4.7 with 66,000 and I'm having problems with miss fires. They happen randomly with no consistency with p0300 and no other codes. The miss fire lasts about 1 to 3 minutes. So far, I have replaced the spark plugs and my camshaft position sensor and have cleaned the...

    I have a 2011 Ram 1500 with the 5.7 hemi. A couple weeks ago it started to misfire and threw the code p0300 and p0303. The weird thing is that if you switch from off to run a couple times the engine runs fine. Any ideas?
