So, I'm looking for some suggestions (and possible a part suggestion) for my recently completed 73 240z restoration. During the restoration I install an A/C system. With the idle adjusted to about 750 rpms the engine bogs down to near stall speed whenever you stop and the A/C is running. This problem goes away if I increase the idle to about 1000 rpms, but then it's way too high when stopping and the A/C off. What I'd like to do install a small push solenoid that activates when the A/C is on, allowing the idle to run at the higher rpms only when the A/C is on. It needs to be a solenoid that can handle being energized for long periods of time and not one designed for momentary use. Has anyone else run into this problem or know of a solenoid that would work in this application? I'll have to fabricate some sort of bracket and mount it somewhere near the accelerator linkage and it would have to be threaded so I can adjust it. Thanks in advance for your help.
