Misfire Cylinder Four

[Slippry]

I have changed the spark plugs and the coil packs and I am still getting a misfire in cylinder four.What is the next step to take?

check the fuel injector, if its not the fuel injector you might be looking at valve damage or a leaky head gasket.

What you can do to trouble shoot is to change the injectors with each other, marking the one coming out no4. if the misfire travels with the injector replace the injector.
Did you check for signal and power to the coil?
