H11BHY 0 Posted March 19, 2012 Report Share Posted March 19, 2012 Hi guys, first post so I hope this is in the right section. Basically car has been running very lumpy and back firing, misfiring and has been down on power for about a week. Changed the coilpack and is still doing this, jacked it up today and noticed that the bottom half of the centre box has come away leaving a massive hole in the exhaust which is blowing very badly. What i wanted to know is, do the symptoms above link up with a broken, leaking exhaust? and also, whether i can get a pipe to replace this box as i want to do away with it completely. Many thanks in advance Link to post Share on other sites
CALICO 130 Posted March 19, 2012 Report Share Posted March 19, 2012 Blowing centre box should not make it run lumpy maybe dirty maf but could be many things try disconnecting the maf to see if it makes any difference. A place that makes custom exhausts should be able to make up a pipe to delete the box i used a company called RSR in Redhill to make an exhaust for my mk1. Link to post Share on other sites
