I wouldn't imagine it's the coil if only one cylinder is misfiring, but it may still happen. IIRC, this code means Cylinder 1 misfire. You need to check the injector at this point. If that checks out good, then you may be looking more extensively.

Alot of times a spark plug may not look bad but it is. I had a misfire on cylinder 3 and i took the spark plug out and it didnt look like anything was wrong with it, but i replaced it anyway and it fixed the problem.
