You probably have a large vacuum leak. With the engine running, listen under the hood for a hissing sound. Check all of the rubber lines running from the intake.

    remove the idle control valve sensor it has two torx screws #20 clean the sensor with CRC Mass air flow cleaner also spray inside the throttle body housing that it goes intro.
    Dont try to use anything else or you will mess it up and have to pay 150.00 for a new one.
    air dry only.. dont wipe it..replace it and it should be all good.

2002 chevy malibu high idleing 3500 rpm when parked
Might need a new IAC, idle air control. If it is stuck open it can cause a high idle condition. Or you could have a vacuum leak. Is there a suction/whistle kind of Sound from the engine compartment that sounds new?

Chevy Malibu 2001 with 89,000 miles idling too high during park
Back to the mechanic - sounds like either an IAC motor or TPS sensor is the problem, but also could be the throttle cable (sticking leaving the throttle not fully closed).

My 98 chevy malibu 3.1l engine makes a whinning noise when driving when sitting idling doesnt make noise just when moving. what is problem please ?
Could be power steering pump or alternator. Best way to find out is to get a a couple feet of garden hose and listen closely to each. Its most likely your power steering pump. If it is, buy a new one not rebuilt.
