Really putting thought into doing this to the Bravada. Will probably do it next weekend when I can get another throttle body gasket. I can clean the tb while I'm at it.
Actually when I first did it my blazer ran really rough when I first started it then ternd it off and back on and its fine. also keep that in mind also if u do anything where u need to disconnect the batt have to do that over again
And that's what the IAC is for it adjusts everything in the car to run properly
