I have an engine code that reads Cylinder misfire. I can't find the ignition coil. Does anybody know how to find it? Does anybody know if there is a diagram of the engine itself?

Welcome to NICO!

It should be located atop the plug through the valve cover.

The question is which cylinder is misfiring as revealed by the code?

When you know this, you can trade coils and see if the fault follows the coilpack or the cylinder.
