My car is a little over the emissions limit and I don't know why. I was wondering if it could be a worn timing chain, could this cause poor fuel burn? I know it isn't the exhaust system as it had a new Cat recently and it barely made a difference. So if any revheads out there could give me some advice, or even tips to just get through the test I'd be very grateful, thanks. :wave2:
