    troubleshooting this damn m20

    my car only starts and idles with the afm unplugged. i am trying to have a list of things to accomplish and check out before taking to a shop. but my car was gving me misfire problems before i went to change out plugs and wires. and after i changed those out my car would have a rough idle around 500 and surge up and down, and now my car doesnt even idle with the afm plugged in when i try to start her.
