has 41k but due to poor maintenance by prior owner, they're more like dog years. I pulled #4 plug and it looked pretty rough w/ <500 miles on it (carbon build-up around outer rim. Cleaned it and switched the coil packs (not plugs) between 2 and 4, reset code. I didn't switch wires. When CEL came back on, unfortunately was P0304 again. How tough is that to switch wires? (I'm used to my old 850 where I can see everything!) What would next step be? Still rough idle w/ cold engine.
