It runs the FV which releases the fuel back into the tank return line.Quote:

I am expecting the same issue with high idling to happen after I install the rebuilt F.D.
Does this AI info seem legit? Is this the best way to test the idle speed control valve?
Can I remove the ISCV and hook voltage to it and watch it move open and closed?https://uploads.tapatalk-cdn.com/202...e04714c47a.jpghttps://uploads.tapatalk-cdn.com/202...b51edffcdb.jpg

I don't really believe the whole vacuum leak theory. If it had an vacuum leak wouldn't it idle high right from the getgo not after it's been running for a while and it is revved up a couple times?

A cold engine requires more throttle to idle. The thicker oil is mostly that cause. The idle system usually runs almost closed at the idle motor on a hot engine. So anything adding to the idle speed can make the idle go into non-controled RPM.Quote:

I don't think unplugging the idle motor proves anything. It does not have a spring return to closed.
What if i remove the hose on idle control and put a rubber plug in it? Would that tell me if the idle control is the issue?Quote:

With the stock idle ECU the idle motor does not close all the way. But plugging the hose may point you in the right direction. My idle ECU will close it fully.Quote:

Tam installed the previously missing plate.

I fixed some loose interior pieces with 3M double-stick tape.
