mass airflow sensor?
Hi!
Picked up an explorer intake yesterday, guy also threw in a cold air intake.
...sorry to interrupt myself here, but there's the intake MANIFOLD, and then there's the intake ..."tube." snorkel. Does it have a more technical name, just that length of rubber and plastic that holds the filter?
Anyway, this cold air intake included a metal mounting post and and a largish diameter ring with a mass airflow sensor built into it, the kind I'm familiar with from my '01 volvo, and I think which most cars now have.
Might be the newer format from the '98 explorer, where this was pulled from.
Does this hook right into our stock system one way or another? Do we have mass airflow sensors at all even, and if so, where are they located?
Finally, I was thinking about EGR (which I would be disabling if I use this intake).
I'm curious: does the computer turn the egr on and off? Is the mass airflow sensor before or after the egr inlet? Because if it's well in front of the egr entrance, then doesn't that mean that you'll run rich because the blended exhaust gases have so little oxygen left?
Or if the computer knows that it's turning on the egr, and I've just sort of left it unhooked, then the computer might try to limit the fuel injectors, thinking there's more exhaust gas (and less oxygen), and I'd run lean?
