It sounds like the electric choke is stuck. Try spraying some carb cleaner into your trottle body to see if it frees anything up.

RE: fast idol stays on

I had the same problem with my 1995 Jeep Cherokee, it would idle really fast. It wound up being a series of things with that vehicle, but essentially a thermostat on the engine was out.

THEN AGAIN on my 99 f150, that was the throttle pressure sensor - replaced it and bam, problem solved. Easy Fix too. Best of luck my friend.
