So my truck has this weird problem when it starts up It sounds and runs like my lawn mower then it smooths out like nothing has happened. I noticed that there is some oil in my intake tube and the throttle body, first thing that came to mind was the PCV valve so i replaced that still having the same issue. I did put a new cold air intake in it but i took it out after a week of knocking and fouling up my plugs now the stock set up is back in. It did throw me a MAF code and i replaced the MAF still the same thing.So far I have replaced the plugs, coil,and wires. I am at the end of my rope, this is kind of acting like the dance of death my old 4.0L did and this engine is not that old with only 25,000 on it and it is scaring me
