Is the IAC changing to compensate for the additional load of the compressor?

Do the iac counts change when you turn the compressor on?

Steve,

The IAC #s do climb BIG time when the compressor comes on...So?

so the iac should be working to provide more air...Perhaps cleaning will help make it effective

should read just like the old one.

be sure not to over tighten it when you screw it back together after cleaning the passages

New IAC did the trick....idles great! You can hear it idle up when the compressor turns on also!
