Thanks for all the input guys - I'll see if I can to it later tonight or it will have to be late next week (work travel
).
I think I have plugged all the holes in the TB - the IAC motor is removed and I have capped/plugged the openings. My idle timing is around 10deg and I can't get it to go lower than 1400 no matter what I do. AFR will go lean/rich, and idle and go up from there.
Jim2, "My 3.2 throttle body had a forward facing brass hose nipple which was about 8mm dia. Make sure this got plugged" - I remember there was a metal of some sort (or this was the idle control knob) here. I tightened it all the way in & simply put a decorative plug on top as shown in the pic. Is this the one what you said should be properly plugged?
My butterfly is as close as it gets - the adj screw is not even touching the throttle linkage. I'll test pinching the brake booster hose next and the union.
Will keep you all posted.
