Interesting, I have to say I suspect my MAF is off (reading less flow than actual).
So, if there is carbonized
oil on it, is shifting the tuning wise? Will its error remain stable over time or will its error keep changing over time?
It definately had
oil on it when I cleaned it. I cleaned it with carb cleaner and Q-tips. Should I try a tiny, fine, wire brush and stronger cleaner like brake cleaner? I have access to a blaster that uses very fine glass beads. I could turn the pressure down, but even that worries me. The idea of a few beads rattling around in my engine makes my head twitch a little too. Although I know this would polish off any carbon, the wires may not survive.
