Ok, I'm resurecting this because I've been messing around with it. I'll post up some pic's soon. So, I pluged the line back in and reset the ECM to get a good baseline. So after a week and half of commuting, I'm satisfied that the ECM is all adjusted and working well. If you check out my fuel log, you'll see a recent drop in mpg, I suppose the winter gas is here. Anyhow, I found that the line going to the intake is a vacuum line. So why would there be a vacuum line running to the intake tube between the MAF and TB??? This line is hooked to some sort of manifold thing, I say thing because it looks like it's check valves, but I need to confirm that to be sure. So I'm gonna run it unhooked, but with a filter so I don't suck in junk, for another week and half and see if the "ghost" mpg gain is real and stays around.
