I have recently purchased a BF Mk2 Force6. I seem to be having a few issues that I am not sure about and wondering if anyone can help. There seems to be a knock or clunk when accelerating and braking some where in the drive line, also when foot is not flat to the floor when accelerating the engine revs seem to hovers rise quickly to 3000rpm and then hover round there for a short period before continuing to climb at a normal rate. Any suggestions?
