    m20 bogs down at 4k

    After swapping chassis' the m20 has been giving me some problems. At first it bogged down around 4k at WOT, but after driving around for a bit i can barely give it 1/2 throttle before it bogs and loses power to the point where it will stall. I also noticed i had a huge coolant leak and once i plugged that up it drove much better, just bogs at WOT again. Could this be caused by improper coolant bleeding? I have been struggling to get the last bit of air out.

    Check your plugs?
    I had really bad jerking, bogging whenever I went near wot. Changed the plugs drove it hard a few times and went away. Test the TPS as well.

        If it runs fine at high RPM at 3/4 throttle, but not at WOT, it might be your TPS as 3vilE30 stated.
