On my 77, there is a screw in the throttle linkage on the back side of the carb and lies parallel to it (NOT INTO the carb) If it is set too high, you may be able to unscrew it some to adjust the idle speed. That's all I've had to do on mine to adjust the idle, but yours may be different. Good luck.

High idle condition in my '83 was not the carb...the EGR valve was shot.

It sounds like Climatic Control got stuck, beffore touch anything else, check the climatic control spring & valve for proper operation.
