whatsup everyone. my car is idling high when i start it, around 1500-1600, and when it goes to drop down, it studders and dies out. what could this possibly be? i was thinking i have a big vacuum leak somewhere but i want to get others opinions who know more than i do. any help would be appreciated. thanks.

Air Idle Control Valve, TPS or MAF issues.

The main thing is the idle control valve (an adjustable screw on older cars). By adjusting this valve, thie idle timing will change on your vehicle.
