lumpy running
I have a 90 quattro with a bit of a problem
its as lumpy as hell between 2500 and 3500 rpm
I have changed vac pipes,ht leads,rotor arm spark plugs timed it up new filters oil fuel pump air the lot
its as sweet as a nut on tick over and when you drive like a granddad but when you give it a bit its as if its missing ............. and its p#ssing me off now
any ideas
