Drove the truck to and from school today. It misses when accelerating, and at highway speeds, pretty much all the time. It's not anywhere near as bad as it was before the distributor was replaced. Before then it would shudder and lurch and try to die. Now it's a light miss that is like the truck is missing a beat, rather than a hard shudder.

I'm going to ohm out all of the injectors over the weekend. Does anyone have any recommendations for things to check? If this is a timing issue, outside of the injectors and the distributor, where else should I look?
