205 GTI 1.6 Cutting Out randomly - Rev Problems

My recently purchased 205 GTI 1.6 has a mind of its own when it comes to its Idle point, and often dips so low that the car stalls, every time the car slows down.

The problem is that sometimes the car decides to behave, and idles at about 1,000 revs, never stalling, sometimes it will idle alot higher at nearly 2,000 revs, and sometimes it will idle so low that it cuts down everytime the car comes to a halt. Problem is, you never know which mood the car is going to be in, which is a problem as im having problems diagnosing what exactly the issue may be. The cars recently had a new head gasket and radiator installed, im not sure wether this problem may be something to do with this.

If anyone can help me with this i would really appreciate it, as its a nightmare right now. Cheers.

Hi, It seems everyone gets this problem at some time or another remove and clean out idle control valve, on side of throttle body. check for steady repeatable voltages out from throttle position sensor. ensure that there are no air leaks on the inlet side of the engine.

There is lots of other posibilities, but these seem the most common. T
