In other cars I've owned, the fast idle at startup (engine cold) usually adjusts to a normal idle in 30 seconds, in just enough time to get the oil circulating. However, with the Bronco (2.3L), my fast idle seems pretty high (1300 rpm) and last 3 minutes or longer. If I shift into reverse or drive with the fast idle, there is an audible "clunk" that that comes from the transmission. When the idle is normal (800-900 rpm) it seems fine. I have a couple of questions: 1) Is my high idle normal?, and 2) Should I be concerned about shifting from park to reverse or drive when the fast idle is enabled, or do I just sit it out until the fast idle subsides? The last thing I want to do is screw up my transmission.
