You need to post what a 302 error code means, or if you don't know, ask for what it means.

p0302 is a cylinder 2 misfire

Still chasing that misfire! Must be the plug...

I swapped the coil out for a new one last night, (just had a few spare minutes to work on the car...)

Still misfiring on cyl 2. I checked all the rest of the cylinders, and they were fine. Just cylinder 2..

I intentionally did not pull the spark plug, becasue I am trying a systematic approach to eliminating the real problem. Tonight I will pull the plug and replace. When I isolate the problem, I will replace all of the coils and plugs.
