Hi all I got a 2000 S3, my first Audi i've had Saabs for the last 17 years but now saabs are cheap(to gm) and a time for change has come, and what a change!! love'in it. I have a few qustions:- 1- yesterday it lost power, I've checked all the hoses there fine. 800-4000 revs off the mark is ok ,but over 4000 its slow to rev, and in 6th doing 60mph if i floor it, it feels like its missing holding back. 2- Which spark plugs? 3- what engine oil to use?
