Locating Mass Airflow Sensor on a 96 E350 5.8L V8

I'd like to get at the MAF sensor in my 96 club wagon to give it a
cleaning but I am having trouble locating it. I know it's gotta be
along the vacuum lines between the air filter and the throttle, but i
don't seem to see any wires coming out. Does anyone have any
experience with this?

Go to www.autozone.com
enter your vehicle year make and model.
click repair info link
then choose componant locations.
select the part and read the location information.

The MAF is in the air filter housing. If you remove the clamp to access the air

filter and remove that part of the housing, The MAF is in the half of the housing that
is still bolted in place.

or is that the air temperature sensor (air charge sensor)
On my car (buick) the air temperature sensor is in the air cleaner ducting
over the
throttle body. Apparently a 2 wire thermo transistor.

Thanks guys, but there actually doesn't seem to be one here. I
disassembled the whole air filter housing earlier today. Seems like
this van has a MAP system instead. Does that seem right? I was under
the impression that pretty much all fords after 94 used MAF. This is a
5.8L V8 with two vacuum hoses coming out of the air filter.

The reason I went looking for it was to (hopefully) remedy a pinging
symptom I've been getting under load at highway speeds. I read that
MAF sensors can get fouled up and give bad readings, so I was hoping
that was it... Now that it looks like I'm dealing with a MAP system,
I'm going to have to try a few different things. Based on a brief
search into previous threads, I've gleaned that the most likely causes
are:

Fuel supply restriction
EGR valve problem
Bad O2 sensor
Bad MAP sensor

Any input on where to start with diagnosis? Or other possible causes?
The symptom is pinging (chatter?) at highway speeds once the engine is
warm. It's especially loud when accelerating uphill or with a load.
Will almost disappear if forced into a lower gear by pushing the pedal
all the way down or turning the OD off. 93 Octane fuel will also
nearly eliminate the pinging.

Thanks!

Interesting. By 94 I would have also assumed it had a MAF.

You're on the right track. Verify the engine tune and ignition timing first. Also

make sure the engine isn't running hotter than normal. A slightly plugged radiator
will cause the temp to go up enough to cause pinging.

According to Rock Auto, the MAF for a 1996 E350 5.8L should look like
