Maybe someone knows what this is.
When the engine is cold, and for the first 10 minutes or so of driving, the engine steps down to idle just fine when I stop. But after the engine starts to warm up it doesn't want to drop into idle and will rev to around 3200 rpm at a stop. When it starts warming up I can "manually" force it down into idle by releasing the clutch in gear while braking, which obviously chokes the engine to a near stall. It may stay there at first, but a few minutes later when the engine is more hot even doing this won't work and it'll just revs back up.
I guess it might be secondary air, I'll try the wd-40 trick tonight and see what happens. If someone else has seen this, please let me know what it was and how you fixed it.
