Its a 1.7 340 and it seems as if its not fueling properly. When driving half throttle it "kangaroos" up the road...

Was sat for a while and when started it missfired abit...

I know its a poor description but any ideas what could be?

Im having the same sort of issues, we've got different engines but have a look at my thread there's some good advice in the replys I had.
