Here is what's happening. When the car is started, it idles from 900 to 1400 and back. It repeats. The only time I can get it to stop, is while I'm holding down the brake, I go into first, let the clutch go just enough so the idle drops to 900 and I leave it there for a few seconds. Go back into neutral and let go of the clutch and the idle stays there. Once I tap on the gas, or drive away, the weird idle happens again. Anyone experience this and have any thoughts? Thanks.
