Re: rpm surging at idle, new IAC didn't help
bought iac off ebay, and it was not motorcraft.
Can buy a motorcraft brand for $60. wondering if maybe I just got a cheap made in china POS and that is why it didn't work.
I will check the PCV hose and valve.... I think I changed those about 4 years ago when I did the isolator bolt repair...
may order the motorcraft IAC and try it... Van has 170K on it I think... original IAC
