Are the plugs correct? and gapped correct? The list is extensive, take it to a shop worth their salt in troubleshooting to check it out. Knowing what the data stream says will give a clue as to what is happening. Is the check engine light on? A bad MAF sensor can do this, egr system failure, weak fuel pump, plugged fuel filter, leaking intake gasket-the list goes on. The $75.00 or so to troubleshoot will save a lot of time, greif and $.

Why is your 2004 cavalier idling to high?

the only thing i can think of is a crack in the intake manifold. my cavalier's manifold cracked and it was idling at like 2500RPM as opposed to the normal 1000-1500, also i had trouble with my brakes and misc other problems because of the crack. if it is just idling too high and there are no other problems i would guess that it is just compensating for the cold. if there are other little issues, i would look into having your intake manifold checked out. gotta take care of your baby because cavaliers are such great cars...... :p
