Re: More High Idle
Swapped out what was a very new IAC valve with the one that was on the replacement engine (original engine had cam sync failure) that I installed a few years ago. Cured the somewhat high/hanging idle. Idles perfectly now.
The only conclusion I can come to is the cheap after market IAC valves are junk, even when compared to a IAC that has 72K miles on it.
Maybe it's just bad luck with aftermarket parts, but this is the second "new" one that has failed.
