Mostly stock 1983 911SC, when depressing the clutch and there's no load on the engine the RPM drops really fast, so much so that when coming to a stop at a stop light the engine will often stall out.

Additionally, every so often the RPM will get hung up and stay elevated for an extended time.

I was thinking maybe a bad decel valve/vacuum limiter.

Otherwise, everything is running like a top.

Thanks for the input!
