Dicky Posted March 28, 2017 Share Posted March 28, 2017 (edited) Just a wild guess but could you have a small exhaust leak that could cause this. I suggest this because my mate had an engine warning light come on suggesting a lamda sensor error or cat problem (I don't recall) and the RAC guy told him it was due to a leak in the exhaust. He sorted the leak and no more error codes. Hope it helps! Edited March 28, 2017 by Dicky Quote Link to comment Share on other sites More sharing options...
Rob350 Posted March 28, 2017 Author Share Posted March 28, 2017 This is what im hopeing, i have a k1 with baffles in so its loud anyway although I seem to think it has got abit more farty and droney recently, but at the same time it Could just be my imagination. I'm hopefully going to get it on a ramp this weekend to find a leak, if i can't find a leak I'm going to get a second hand cat off jez from Horsham. Thanks for the response, im a little bit more optimistic now that its a leak... fingers crossed Quote Link to comment Share on other sites More sharing options...
