I assume you meant to say 1,100 rpm; not 11,000 rpm. You wouldn't want a 6,000 rpm idle either.

Check out the SEARCH facility. Key in FAST IDLE and only search the TITLE area for starters. There are many things that could cause a fast idle to include:

- faulty idle speed controller/actuator
- sticking throttle linkage
- TPS(throttle position sensor) out of adj.
- Vacuum leak
- Bad throttle switch
- Air plate position sensor

These a some of the possibilities.
