I'd searched on here and obviously, there are quite a few of these threads, but here's another--I just couldn't get mine to run right, at all--hanging idle, idled high, etc. I'd adjusted the TPS with a voltmeter/ ohmmeter to read .95V. I'd adjusted the idle bypass screw in a few positions (closed, 1/4 turn, more than that)--no go. I'd adjusted the stop screw properly--still a problem. IAC is good--it was running fine on my stock TB, and was fine after I'd put the stock TB back on the car. After the 75mm wasn't running right, i'd also put some rtv around the IAC gasket, just in case--no dice. I'd sprayed around the throttle body for vacuum leaks--nothing.
