Good Day All

I have a '68 Super Bee with a six pack. My problem is with the idle quality. When it is started (cold) it will idle at approx 600RPM . As it warms up the idle will increase to approx. 1400-1500. It will not idle down. The solenoid will either chatter or not work at all. It is wired from the ballast resistor (continuity is good). A quarter turn on the curb idle screw will drop the idle to 7-800 RPM.

I tried to jumper the solenoid from the battery with no result. I think the solenoid is FUBAR.

However, this is not consistent. Sometimes it will idle great, then the next time you accelerate the idle speed will jump back up.

I really don't understand this.

Any/All responses are welcomed.
