I have a 98 Audi a4 2.8 quattro that was running great and when I left the store it would not start until the third try and it rev'd up on its own and died out now won't start at all??
It rev'd up to about 2 5 I threw it in gear and
died out it rev'd up very weak so my first
thought was something in the fuel system
does anyone have a clue what this could
