You might want to start by having your iacv, or idle air control valve cleaned. It could also be the tps, or throttle position sensoe. Sometimes after a period of time these things ccan come out of calibration. It is best to have the vehicle looked at by a trusted mechanic near you and that way he or she should have the things that it takes to prevent this problem for you.
