Audi a4 2.0t what's wrong?
When my audi is at an idle it revs up but
goes back down and I can't pull out in
front of anyone because it don't seem to
want to go on the start but as I get going
things are fine until I hit a hill and I lose
speed. It also don't get all its rpms. Could
this be a turbo problem or something
else?
