Thanks for he detailed question, so can you confirm spark output for that coil? Here is a video to show you how to test it, keep your hands away.

If you have spark we can continue, also does the engine run okay and do you here a light ticking noise when the engine is cold? If so you may have a flat camshaft, you will still have good compression if the lobe is worn but you will still get this code. Please upload a short video in your response of the engine idling form under the hood, so I can see what's going on.
