Sly said:Hi All, I just got my solenoid to start working on the Pacer. I'ts a 77 w/a 258 w/BBD. I thought the solenoid was for kicking up the idle when the A/C compressor kicks in. I thought it was supposed to shut off when the A/c was off. Mine is on all the time now. I had my idle set nice and low (where I think it is supposed to be), but when my A/c kicks in, it struggles to run. Any ideas? Thanks! Sly Sly, It sounds like your solenoid is a throttle stop solenoid. It stays energized (extended) all the time while the ignition is on and then when you turn off the ignition it retracts, allowing the throttle plates on your carb to completely close, preventing run-on. I'm sitting here at work with no AMC references but I think you adjust the warm engine idle by manually turning the solenoid shaft in or out, while it is in contact with the tab on the throttle linkage. The cold idle is adjusted by putting the throttle on the second step of the choke linkage and bending the linkage as necessary to achieve the proper rpm. If your solenoid is designed to be an A/C solenoid it will only be energized when the A/C is on (power supplied to the compressor clutch). The warm idle without A/C would be adjusted by the idle screw on the throttle linkage (while the car is in drive with an auto tranny). To adjust the idle with the A/C on, the solenoid shaft would need to be turned in or out. Folks correct me if I'm sooooo wrong here.
