What causes a fuel injection valve to misfiring?
Carbon buildup on intake valves and injectors has caused misfiring in this direct-injected engine. This valve doesn’t look too bad, we have seen much worse. In many modern cars, especially the ones with direct fuel injection, carbon buildup on intake valves (see the photo) and the injector nozzle can cause a misfiring.
How to diagnose an engine misfire & solve it in quickly?
If engine has COP coil than you must check the P0200 code series to your investigations. You must check the ignition control module. This is one of the tricky to check, if the misfire happen in the one or two cylinder, you can swap the suspected one with the good one for a quick check. Check the ignition timing also.

Why does the piston clearance go away in a late model engine?
The piston-to-cylinder clearances in most late-model engines are much less than they used to be to reduce piston rock and noise. So if the piston or cylinder gets too hot, the clearance goes away and you get metal-to-metal contact.
