Thanks Paul D.

I could not get to the L Cam sensor, even after removing the electric air pump on the left aft of the engine bay...
So I decided to take the rear bumper off (again), lower the engine a few inches (I was going to replace the engine mounts anyway), and remove the right side muffler (I had gotten a new cat pipe to muffler clamp in).
I cut the old clamp straps with a hand held grinder, and (after much PB Blaster) got the 3 13mm nuts off the inside of the R muffler bracket, and pulled the R muffler.
Doing all that, gave me access to the #4 coil and plug!
In order to get to the L Cam Sensor, I had to loosen the rear engine mount cross bracket from everything (still couldn't pull it out though), and that gave me JUST enough room to get at the L Cam sensor.

So far, no CEL or fault codes!
