Really Fast Idle, need help

Insaine idle. I have a 89 and its been running great. This morning when I left for work for some reason the idle just kept going up. It was to the point where I was having trouble holding the brake at stop lights. When I did put it into park it sounded like the throtle was floorded. It was screamming. Any idea's I checked all ther usaual stuff.

Thanks
Kenny

Throttle Position Sensor or Coolant temp sensor will cause odd idle issues....

Also, make sure your throttle isn't sticking....

does it throttle up as soon as you start it or after awhile?
I would suspect the iac is stuck..go grab one from the junk yard for a couple bucks and throw it on there.Or take the one you have out and put a penetrating oil in the piston to see if it'll free up.
