Default Re: TB removal and then some!!!

Well when things happen, they happen......after changing out the battery and the alternator, I decided to remove some of the white grease on the throttle plates.....might not be the wisest decision I made!!!
Noticed after that, the idle crept up some, not like before up to 1100 rpm's when stopped, but more like 800-900 rpm's. Almost the same situation, if I let the clutch out some, the idle would drop. Or if I'm at a stop and I blip the throttle slightly, it will drop down. So today I put the Tech 1 on to check my IAC's and once again they are @ "0" at idle. And this time with any acceleration, they go as high as 16-17 and that is it. Other than that the engine is running great, no problem going through the gears and getting the secondaries to open up.
I even swapped out another IAC and the same result. So kind of back to square one to a point, have to get out the FSM and try to figure out what is going on. Also setting the min-air screw did not really have an effect on the idle one way or another, it just stays the same......around 725 r's or so until I drive and come to a stop.....
