I'm still learning to make sense of the data on my scan tool. Today's topic is the MAF sensor...
If I understand at all, I should be seeing ~4.2 gr/se for my 4.2 6 cyl engine. At idle, I've got anywhere from 4 to 7 or 8-something, but driving, both around town speeds and on the highway, it can be around 30 gr/se...glanced at it at one point and saw 64 gr/se. It tends to bounce around a lot, even at constant vehicle speed.
Now I understand that going 70 mph, more air is going to be rammed into the air box, but are those numbers too high, or is this normal?
