    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?

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