    Ok gang started this a few weeks ago. I changed throttle positioning sensor. I changed the plugs and wires. I even ran a can of seafoam through the gas no codes. It has never given a code. I’m wondering if it could be the map sensor or air sensor any thoughts?

    Ok thanks.
    I’m even thinking maybe the coil.

    Swapping the coil to another cylinder could help diagnose if the misfire follows
