So. my T5R failed its MOT. failed for De-cat pipe. BOTH licence plates are illegal. and emisions are way to high Co 0.492% n allowed like 0.100%. so i need a cat converter. 2 new plates and all with ££££ all money left over cause the money i spent servicing it and trying to fix the misfire DIDNT WORK! she still coughs on idle and on occasional pulls will just completely cut out. im seriously confused n need some help if anyone has any ideas?
