Ran fine last night, wouldn't start this morning

Maybe it wasn't all of them or that plugs at all, but after I put the old plugs in, the car started right up. I was going to try iridium plugs, but if there is a more reliable solution let me know. I may just keep these in as they seem to be running better than the brand new ones I originally bought to change them out with.

I'll see how long this lasts though. It was indeed odd, but everything else looked good. All the connections seemed to be as they should. If it does happen again, and I certainly hope it doesn't, I'll have to tackle it.
