Mk3 1Z TDI Juddering + Lumpy Idle
« on: 27 November 2009, 14:56 »
Hi Guys, Sorry this is my 1st post but ive only just recenty got myself my golf lol

I do how ever have 1 little/large issue & I was just wondering if anyone can shed any light on this issue im having


I own a 1994 Golf 3 TDI(Code 1Z) and its developed a lumpy idle*Between 800-900K* and stutteres like its suffering from some sort of air/fuel loss!

Ive bled the fuel lines as there was air in them and also repaced the MAF as it was rather grotty.

Any Advice is greatly appreciated

Cheers,
Steve
