    MAF and TB are clean. Also swapped with known working from another car.

    Interesting thing I found last night if I unplug the MAF the misfire goes away. Confirmed with 2 different MAF sensors that work fine in another car.

    try tapping on the maf top, sometimes they clear up with a tap or two.

    also check the maf pig tail wires for damage.
