Ok I know this has been asked a million times....
I have been having a high idle problem, I can not get it below 1,100-1200rpm.
I have cleaned n replace the IAC, cleaned the TB n EGR spacer, tried clocking the mass air sensor, checked TPS voltage (0.89), also tried 2 reset base idle by disconnecting the battery for 30 mins, IAC un-plugged, ect, ect...Still cant get it below 1,100. The only thing I can think of, is the TB blade is worn n getting blow-by? Besides the idle it runs great. What little mods I have include: UPR in fender cold air intake, off road h-pipe, mac equal length shorties, elect. fan, new alt., new cap n rotor etc... The motor was replaced recently, but kinda had idle problems w the old motor also. The new motor was heads, block, lower intake. Everything else stayed the same. So I assume I transfered the problem from one motor 2 the next. HELP...
Thank you
I also changed the ACT, and ran codes...codes= 94 AIR system inop, 44 AIR system inop, 13 idle speed or air bypass not controlling idle. I took the iac apart n was very clean n free moving. Did not see the iac motor moving at all. Not sure when it should move though.
