Idle Too Fast
My 94 1.0 with auto trans has a similar problem. I temporarly fixed the it by pulling off the small hose from the throttle body that comes from the Idle Up Solenoid and then plugging up the small vacuum pipe with a rubber cap. I also plugged up the open end of the hose to keep the inside of the solenoid clean. After doing this, my idle speed dropped to a normal speed, possibly even too low. The purpose of this system is to allow the ECM to increase the idle speed if it detects that either the parking/ headlights, the blower fan, the radiator fan, the stop lights, or rear window defogger are on. If after you try this, your idle speed is too low, you can probably raise it with the small screw on the side of the throttle body.
Hope this helps.
