Hi all, I bumped a curb the other week and broke the wishbone. All the work was carried out by a garage but I've noticed that when I get to about 3000rpm in any gear, it sounds really rough and I lose power, not completely but you can feel the car slow down. It sounds like the exhaust is blowing but its not? When at stand still though it seems fine? I really haven't got a clue, any ideas???
