Hey guys, I had a pre MOT 5 weeks ago and the car failed on emissions. I bought uprated coil packs and spark plugs as she was running a little rough. They took so long to come I’ve just had them fitted today however the emissions are still a problem so, my thoughts are that the cats have gone. My MOT is now due next week and with my work schedule I can’t really do much about it. I have a bottle of Cataclean and a dream. Has anyone used this product and did it work? For reference I have high flow cats not stock.
