This would be one of those times. If there is one thing I've learned from my ever problematic DSM, it's that when there is a misfire, go after the most common cause first... plugs and wires. Compared to determining an injector failure, fuel rail clog, bad coil pack, or other potential problems, plugs are easy. This is fixing the misfire... and if by some slim chance it turns out that it isn't stemming from the plugs, I will definitely let you know.
