Well when I was driving back to school yesterday (took 6 hours), I stopped and got some gas. Then hit traffic inched forward for maybe 30 minutes. And then after we got going again, I noticed that in vacuum between like 5"-18" about, the car would bog down for just a second then go normal then bog down again. The zeitronix showed it going way rich (10:1 or 9:1) when this happened. Car runs fine in boost and in vacuum greater than 20"hg. So either the megasquirt is deciding to add fuel for some reason in that area, maybe the map sensor is seeing less vacuum than is there, I'll have to take a log but my laptop battery is crapping out on me. Or maybe theres something wrong with the ignition, but then I would think it would happen under boost as well. Any other ideas?
