Re: 5.3 FI swap... acting carbish?
As far as I know, the IAC is working properly, no codes are showing if that's what you mean.
The throttle body has been ported and the "stop bracket" on the body itself was milled down for a Wider Open Throttle, if you will... The screw for the throttle blade stop, i don't believe has been messed with...?
The throttle blade should be fully "closed" at idle, correct?
