Hey guys, wondering if you can help me, I've got a 1.2 16v clio2 and on cold starts its runs on three cylinders, but once its warmed up it runs fine and misses occasionally, no loss of power once warm and no management light, I've replaced the coil pack (due to the end of cylinder 3 snapping off on plug) and I been advised it may be a leaking injector. Just wondered if anyone could give a bit of advice?
