Right, I'm getting really really fed up with my car now, it's been running crap for a while, and it's doing my head now! Apart from running unbelievably slow, when I come off the throttle it jerks like mad, and all speed from 0 upto 70+. Does this sound like it could be a "sticky valve"? If that was the case would my emmissions be up (emissions are perfect)?
or could it be timing related?
