IAC appears low

[hflwyo]

Just to start car is running fine with no problems, but I noticed that the iac is at 0 in idle after warmed up. When started it is in the 30's. Tps is fine at .44 at idle. Should I adjust the iac or leave it because it seems to be running fine. Idle is about 875-900. I know the vehicle is supposed to be in closed loop to do the iac reset but I have a turbo tweak cheap and it says car goes back to open loop at idle. I have a new delco iac in box should i try it to see if it chages? Any info would be helpfull thanks.

You may have a slight vacuum leak or the throttle stop needs adjusting. Go through the IAC cleaning and setup procedure first. I doubt changing the IAC will do anything.

Ideal is around 10 hot idle. If it's running good leave it alone.
