I've been told the hesitation problem on my 3.8L V6 is caused by a
faulty Mass Air Flow Sensor. Now, as these are pretty expen$ive, what
would happen if I disconnected the MAF Sensor from the air duct to the
throttle body? I would think this would be a good way to see if this
particular part is bad without putting a new one in.
Let me know what you think!!
I think you should inspect the MAF. If it's clogged up, you will
be able to tell. It *can* be cleaned if necessary.

If the maf is the problem, a good cleaning will usually
correct it. They seem to collect a bit of a coating from
the contamination in the air over time. You will need a
torx security bit to remove it, some residue free electrical
cleaner and a cotton swab to clean the small wires. Be
gentle with them. There are pictures of maf cleaning with
instruction at many places on the net.
While your are cleaning, it would be a good idea to clean
the throttle body with a good TB cleaner. An old tooth
brush helps get the job done there. The TB usually has a
tag telling you not to clean it. It has a yellow coating to
resist deposits but after a while it, too, will become
coated and obliterated. Ford sells a very good TB cleaner
under the Motorcraft brand. Although I have never seen it
in the aftermarket, it is probably out there somewhere.
