prob when cold

[rick247247]

well i have got k&n 57i induction kit, sometimes when i rev it when it starts up the revs drop n it starts to struggle n stutter but after a min of runnin its fine. i guess i will have to get someone to check it out, oh it also always makes a sort of ratterlin noise when im drivin alone without my foot on the accelerator could that be a prob, dont you think its nething to do with the air sensor then, it looks a bit fraid where my induction hose has been sitting on it thanks neway for your help
