When you reset the pcm you gotta give it a bit of time to gather up data.
It takes a bit more time to make its adjustmemnts based upon that data.
In a nutshell ... it needs to be exposed to all possible different idle conditons several times before it will become stable or has quit its adjustments.

In my experience, running that bleeder out more than about 1.5 turns can lead to a nasty vac-leak-like situation. I'd run the bleeder back in till it's about 1.25 turns out, and try it again (you'll probably have to reset your hot idle since you used the bleeder as a crutch).MI95Cobra said:well...i cleaned the maf and its a new iac....so i'm really confused...my air bleeder on my throttle body is almost all the way open.......
There are a couple of different schools-of-thought with setting the idle. I choose to disconnect the IAC (on a hot engine with all accessories turned off). Then I set the idle where I want it (don't stray too far from the commanded idle). Now you know that this will be your hot, no-load idle, even if the IAC takes a total dump (you're simulating this because the IAC is disco'd). You only need the IAC to function to help with loads (big electrical loads, AC, etc) and when cold.MI95Cobra said:no....do i need to disconnect it?????
All this info has been in the links I posted.MI95Cobra said:the threaded rod???? sorry i might call it something else...
No problemo. I call the stop screw a threaded rod or threaded shank.MI95Cobra said:sorry i called it the air bleeder screw...
