2007 Chevy Tahoe. Recently installed new non-dod lifters, non-DOD stock cam, non-dod valley plate (kit from TSP). Changed DOD and DOD DTC settings and turned off flex fuel in HP Tuners and started her up. Random Misfire at idle... seems to be concentrated at Cylinder 4 to start and then Cylinder 2 jumps in the mix with a few in Cylinder 3.
Have checked for spark and fuel on cylinders 2 and 4. Plugs looked good but replaced them anyway and checked spark again. Confirmed all fuel injector wires are connected properly. Compression in cylinder 4 is similar to the others. Cant quite figure out the source of my issue. Log and settings below. Doesn't look like a vacuum leak per fuel trims but they appear to give up shortly after startup.
Any help would be appreciated.
