Hello. I couldnt help but notice this problem. I am getting real close to buying myself a 97 golf GTi 16v so was looking around.
On my honda prelude I had a very similar problem a little while ago. My idle would be low and then it as I was braking and diving on the clutch the car would stall. And also happened while slowing for lights etc.
In the end the PCV had to be replaced and this fixed everything. Positive crankcase ventilation valve or sensor I think its called.
I'm not sure if the gti has one of these as my honda is older.
anyway.
Steve
