Howdy,
I've finally got my Riviera through most of it's more fundamental issues and am now trying to tune it. It doesn't want to idle at the commanded rpm as well as I'd expect and after reving it up and holding it the IAC starts whistling and it continues whistling when it returns to idle.
I've adjusted the "minimum air" setting on the throttle blades with the TPS removed so I can get it to idle close to where I want it without the TPS acting like it's going off idle.
If I press on the IAC after it starts whistling the whistle stops and the idle doesn't degrade. I pulled it out and greased the O-ring with dielectric grease (decided it was better than PTFE or white lithium) and cleaned the pindle and seat, but that didn't really change things.
I have a spare IAC that I'm thinking of throwing on, thoughts?
Thanks,
