and...

Does anybody else actually use the clamp on the MAF-to-throttle boot for what it's intended for? Mine takes a little more than 5 seconds to remove. Gotta loosen the clamp.

............ not with you here..... it was you who suggested an hour... I've seen various waiting times suggested by various people at various times. But unless the car has been modified in some strange way, as Wally suggested, then no more than a couple of seconds are required.

No one thought to reset the ECU after cleaning the MAF.

Rather than a 'yeah, that's right' you niggle over the reset time.

John Speake

I think that self adaptation would soon take up any changes required, but your suggestion would work fine too :-)

I'm not niggling about reset time, except that 1 hour is rather excessive.

Having seen all sorts of times quoted in the past, I wanted to give a more fact based figure.

Yes. Gotta orient the clamp so the worm screw head is accessible from the passenger side. Several manufacturers make a long flex-shaft nut driver that make this a 30 second job. A 6" 1/4"drive extension, u-joint, and 3" extension also works.

Got the tools OK and use them. But a few cars that have been here have MAF's that just lift out of the boot and drop back in. If the lower air cleaner housing didn't keep them in place, they'd fly off in the turns.

On the ECU reset, the barrey ground is lifted for anything more than adding fluids, so it's already disconnected for MAF removal.

My car 'learns' that it's pretty much all downhill for the first 8 minutes of running after power is restored. It learns better if I disconnect with the engine already warm, car closer to the bottom of the hill abd normal driving. Difference is worth maybe 1 MPG averaged out.

Until the 3" extension and u-joint falls off into the valley of no return.

On an 85 you can get to the clamp if you align it straight forward.
Straight through the intake runners.
You do not need an extra long driver.

I never had bolts on the inside of the lower part of the airbox.
With them you can see how they will hold down the MAF in place

Looks like 'Gunk' makes a MAF cleaner product - Anyone ever try it?
