Hi, first post, here we go. I have a 2009 mk3 clio 1.2 tce. It was running with a misfire so I changed the plugs, leads and coil pack but the issue continued. I have now changed the corresponding fuel injector and the old one was full of crap not letting much fuel through so I think that was the problem. However, even though the car performs better now it still isn’t perfect. So my question is does the fuel injector need to be coded in? It is a Bosch injector and the part number is 0280158335. Any help is massively appreciated. Thank you!
