1996 VP 5.0 EFI.
It is a 1996 VP 5.0 EFI that may have been converted to EFI-not sure. However, it was rebuilt and it sits in a 1996 Regal Commodore 258.
The engine runs great at idle and seems to at speed the little that I had it in the water. However, it idles way too high--1800 RPM after warm up. It will not drop down and there is no adjustment on the throttle body. I believe idle should be about 600 RPM.
I understand it may be the IAC? Any other common reasons this might be the case and suggestions on how to resolve it would be awesome.
