Default iac issues

ok the stupid thing is getting on my last nerve. car idles at 1050. the iac maxes out, turn the blades a little she then decides to zero out. by the word a little i mean less than a 1/4 turn, maybe close to an 1/8th. it will not stay in one area it floats for a few seconds then either maxes out or closes. the idle does not get affected. i have closed the blades and started fresh, it did not help or change. my kpa is around 70 but i have a decent size cam in it. the main thing i am trying to resolve is ther fact it wants to stall when you put it in drive or any other gear. now it was a six speed car and now has a th400 in it. is there any way to bypass the iac? to get the car too know that it is going into gear. so the idle will hold and i dont have to tap the gas to get it to stay alive. my tps voltage is .62 and postion is 0%. the wideband reads high 13s to low 14's, if it matters to anyones thought process. oh yeah its a monoblade i knew that info should be in there but almost forgot it. what can i do that i have not thought of yet?

Have you checked the throttle position sensor voltage?
