How do I 'set' the TPS and IAC...93 LT-1 ?
Someone mentioned they set their TPS and IAC and their car has never run better. I asked them how to do it, and they never responded back.
Recently I put a new TPS sensor in, at WOT the new TPS registered 4.06 volts which showed 99% throttle position on my Auto XRay scantool.
However, my old TPS sensor showed 4.62 volts at WOT and 99% throttle position on my auto xray.
I figure I might be 'ok' because it still shows 99% throttle (somehow my ECM learned that 4.06 volts meant WOT)
However, I am still curious as to how one 'sets' both IAC and TPS
I should mention my car always seems rich, with its current mods, at idle.
I have a 93 LT-1 w/hot cam kit, ed wright chip, LT headers, no cats.
Any help would be appreciated,
