like vr6 said, what fuel you using?
But also you better get your timing checked as it sounds well out

I think your right K-Jets were up to 85 I believe on the 8v and the mk2 16v was k-jet. I know my 89 16v has a K-Star chip that is suppose to help it run on unleaded fine. Don't know if it makes much of a difference though.

8v had k-jet until 1988, all 16v are k-jets.
K-jets require 98RON fuel, so lead is not required.

wats the diffrence between k jet and digi? ::)

k-jet is mechanical fuel injection
digifant is fully electronic fuel injection

tell the difference by looking at your airbox, if it has loads of fuel lines coming out of the top then it is k-jet.

this is the problem with the k jets its older technology
i had a 84 gti and i ran that on 95 unleaded and never had pinking it was great just one problem i had was the old filter seal blew out on start up once and all the oil drained out of it :( 2000 miles later the bigends were rattling.... so i got rid of it....

the digi's are much more advanced they automaticly retard the timming if pinking occurs by the knock sensor...

sound like his ignition timming is way out!
