Are you trying to use the mustang IAC because you have the ford TB? I'm not sure the Ford IAC is actually working, it may just be in a position where the idle is good enough to run. I'm pretty sure the Ford IAC is a stpper motor type IAC. The '01-up Neon PCM's won't drive a stepper motor IAC. They use a linear solenoid style. Maybe try installing the neon IAC and resetting the pcm. The IAC should be installed in the position shown in the pics in this thread: http://forum.2gn.org/viewtopic.php?t=25866
The paper gasket must be used the "o-ring" will leak.
Did you cut the wires to adapt the IAC? maybe they're switched? would be hard to do since they're color coded, but had to ask.

Probably shouldn't listen to anything your penis says, that guy's a dick.
Patience, of course, is a very powerful weapon, but sometimes I start to regret that it is not a firearm.
Too much time spent here is a sign of a bad case of Ownaneonvirus.

Polarity on the 2-wire PWM solenoids doesn't matter. You can reverse the wires and it doesn't matter.

Yep, my bad, wasn't thinking about it being a coil.
