That's what I thought too, it actually feels like an ignition problem. But everything seems to check out ok. The only thing that I found suspect, was that the + side of my coil has 10.5 volts while the engine is running. But I don't think that would cause my problem.

I have a wideband o2 sensor, in going to put it in my exhuast just to be sure I'm not running out of fuel.
