Thanks for all the help, but I think I'm just going to save up for Mass Air. Even if it is possible to get this thing running on SD, I think I'd be better off simply converting to MA, and getting it over with. It's money I didn't want to spend, but I could probably spend more than that trying to get the SD to work.
What if the MAP sensor wasn't hooked up to any vaccuum at all?? Ha! Ha! Even though people had mentioned the MAP sensor, I honestly didn't know which one it was. Well, I found out what it looked like ( little plastic box bolted to firewall behind intake, right? ) and when I checked mine, I found that the vaccuum nipple was completely broke off. It must have happened when I first pulled everything apart, and I just forgot that I'd done it. I sure am glad I'm such an EFI newbie, otherwise I'd feel really...
Yahoo! That makes a world of differance. It will puff some smoke out the pipes as I rev the engine, but hold it at a steady rpm, and it runs clean. It still won't stay running at an idle, but I haven't adjusted the idle speed yet. I'll have to do that next. I've also got much better vaccuum now. I'm thrilled! It's far from running 100%, but I'm a WHOLE LOT closer.
