Hi there
Have you resolved your problem?? having simular issues when accelerating whether it is hot or cold, pulled the plugs out to check and they do seem a little coked up on the tips, could this be anything to do with it or not? one thing less to clear off my list before i start on plugs,cap,arm,fuel pump and filter etc etc etc.....
Also seems to run rich smells a little, yet went straight through MOT check with no issues???
Thanks for any advice, bloody annoying this is....
