2006 Ram 1500 stuttering and code P0301
I have a 2006 Ram 1500 Hemi, and just after filling up with fuel I got about two miles down the road and it began stuttering and I got a check engine light. I checked the error codes and got a P0301 for a misfire on cylinder 1. At first I expected it may have been bad fuel but after driving a little further toward home I checked the codes again and still only had the one code, so it's only a single cylinder. Am I right in thinking the other possibilities are plugs, coil, or fuel injector? I have a couple questions: 1) which cylinder is #1? and 2) can I test or rule out any of those components such as a coil pack or injector without specialized tools? Thank you!

Thanks guys, I'll try swapping coil packs and see what that does, I did some more digging on the cylinder numbers and it looks like #1 is front driver's side. @HeyYou I know, I'm really hoping it wasn't bad gas I filled up a little over 20 gallons, but if that's the case and I can confirm it I will be having a chat with the gas station, I already gave them a call when it happened so they have a record of it in case that was the problem.

ok, I swapped coils between cylinders 1 and 3 and started it up, the misfire stayed with cylinder 1 so it's plugs. I picked up a full set of plugs and started changing them out, here's what I pulled from cylinder 1. I've never seen anything like that before. I'm not done yet, but I got through a few cylinders and the other plugs were definitely needing replacement but they were still gapped. I'm wondering if somehow MDS could have contributed to this? I haven't got to the other cylinders that are shut off by MDS so we'll see what those look like.
