RESOLVED!
So my rotor, the distributor cap, and the bad coil were all replaced today and the car runs as good as it ever did... I forgot how peppy it once was.
It did throw another CEL on the test drive (oxygen content), but I cleared it and the CEL never came back... I am hoping that the ECU just hadn't adjusted to the more efficient ignition or something... :/ But no mater what, it is running perfectly.... and it looks like I might be back into 30+ mpg! :thumbup:
