If it is drivable, go to any of the chain auto parts stores and ask for a free scan of your computer to get any stored error codes. A fast idle can often be caused by a vacuum leak; check under the hood for cracked or disconnected vacuum lines.

I think you have a short where the wiring harness plugs into the fuse block .I'ts located on the

burned wire.
