Idling problem

sa friends 97 model 106 gti I have had an irregular speed increase and landing in my car recently, now occasionally I hit the clutch while going through the passage and at normal idling, the idle was correct when I moved up and down the cable of the valve under the idler engine and it became irregular when it was released. I'm waiting for your help thank you ...

throat throttle, this idle chronicle may be a problem in the 106s, idle valve cable sockets may have oxidized, maybe disconnect the cable while the car is running at idle

throat butterfly clean .. okay let me try it again thank you

Teacher, I was in the same trouble, thanks for the friends in the form, they offered me to clean the rotation sensor and the improved tip of the rotation sensor was oxidized.
