I am having a slightly similar problem. Occasionally when I start the engine from cold the engine fault light comes on. Misfire on cylinder 2 is detected. If I clear the fault with my Autel gadget the fault clears and everything is perfect until the next cold start. Although sometimes I can have several cold starts without the light coming on. I have changed the plug and the coil on that cylinder. Yesterday I replaced the injector. The new injector looks differrent from the one I took out see photos. I was sure I had found the culprit but no, this morning the cylinder 2 misfire fault came back. I am hoping that the plug may be fouled (if the injector was faulty) and it will either clear itself or a new plug will do the trick.
