my uk rev5 n/a when cold is spluttering and running generally rubbish


under load it feels almost like its misfiring as its gets warmer it eases but by no means stops but is a huge improvement over when cold


any ideas it started the morning i went to get my exhaust fitted but was only slight when cold then dissapeared when warm, but now is horrible and certianly get a lot worse


any ideas suggestions would be greatly appreciated


thanks
