So, yesterday after installing yet another return line kit (O rings and hose etc) I'm too old to be ******* that engine > > > >I discovered the "high idle solenoid" yup, now I remember many-many-many years ago turning it up a bit.
It reminds me and looks like the AC solenoid on my 81 Corvette that raises the idle when the AC is turned on.
Anyhow, I removed the connector from the top, rotated the shaft 1/4 turn, sprayed some WD40 on the shaft and it]s 'lazy' meaning it kicks in late.
Sooooooo, if I put 12v test wire to the solenoid is should pop-out... correct?
And if it does, then the temp sender is bad. If it doesn't the solenoid is bad.
