    Hullo!

    Originally I was having a misfire in cylinders #1 and #3, I went in and changed the spark plugs + wires as the truck now has 300,000 miles. I found oil in the spark plug wells of said plugs and changed the spark plug tube gaskets.

    Now the truck runs fine when I start it up cold. After I have already drove it, and I start it up again, when it is still warm, it will get the check engine light and misfire codes in #3 and #6.

    I have checked;
    - coil packs
    - wires
    - spark plugs

    Whats next? Fuel injectors?

    Also! It will sporadically go away. Sometimes, when I'm driving.

    And ok deal. I had a feeling it was something like that, just didn't want to start the work.

    Haha true I am. I was hoping that someone had this exact same problem before. Always worth a shot. Might take it apart and look at my injectors as the next logical step. Im starting to feel like a lot of time has been spent diagnosing it though.
