Please help me. I have a 1992 golf gti 8 valve. Tickover is uneven to such an extent that it is dangerous to drive. My mechanic has cleaned the idle valve but it didn't fix it, so I'm looking for a new one. I've tried Volkswagen and big boys toys, they both want £293 plus vat. Do you know where I can get one cheaper, or should I pay for the real thing?
