Bulletproof 0 Posted January 7, 2011 Report Share Posted January 7, 2011 Hi I have a problem with my vr6 I had a scorpion cat back exhaust fitted about a week ago and everything was fine but I've just come back from working away which was only two days. started my car up and it's now struggling on idle and when I drive like a juddering. If anyones got some advise I'd be really grateful. Link to post Share on other sites
