Hi all, I have just bought a 90 model ultima with a 2 litre and auto, the car idles fine when the engine is warm but it needs to be bumped up a bit for when the engine is cold and also for when the air cond is operating, can someone tell me where the fast idle adjustment is and how to adjust, in the past on other vehicles there is a solenoid but on this model I cant seem to find one, any elp much apreciated, regards Brett

Hi Folks- I just finished cleaning my throttle body butterfly with cleaner and a rag and now the idle is about 1200 rpm, not 800 . All the hoses and connectors are in place. The cleaner is supposedly safe for sensors, etc... any ideas? Thanks
