Do I need a new MAF?

[Paul Clark]

BLMs 160 at idle.
128 at anything over 1100 rpms.
Disconnected the MAF and they dropped down (but kept bouncing) as low as 108.
Is the normal, or do I need a new MAF, or...?
Thanks

Could be. What's the MAF reading at idle, and above? All the other numbers looks normal,, could be O2 sensor too. Car stays in closed loop, etc.?

MAF at 5 - 7.
New Denso 02.
Thanks

That Denso O2 sensor may not be getting hot enough at idle to "fire." I'd recommend a genuine AC Delco unit, with the purple wire, no matter what....

I sense a debate coming on -
Denso 02's vs. AC's.
Someone who has used both needs to check in here.

My Denso is working great. 122 BLM at idle. Don't see how a Denso doesn't get as "hot" as a Delco. They both get up to closed loop temperature, trust me (or just put your hand on it) .
