Hi, would appreciate any help, or advice, I have a Mk2 GTI 8v 1991, about 6 mths ago it started playing up; the engine would surge when cruising along at 50-60. Occasionally would stall, now the engine actually cuts out (same speeds) dangerously as I have to drop down 1 0r even 2 gears. - anybody else out there suffered similar problem? would appreciate any help, before this happens when overtaking...
