Title: Vacuum leak on 1.8t GTI
Post by: robmac159 on 26 April 2010, 18:46

I'm having trouble with my 1999 AGU 1.8t VW Golf GTI, basically the idle is very lumpy, I've replaced all the coil packs and spark plugs.

Do you think it could be an issue with the inlet vacuum system?

Any advise on how to fix would be great thanks.

Cheers. Rob.
