94 Explorer giving lean on both banks

I have a 94 Explorer with the V-6. Will not run at full throttle, sometimes
will fall flat at hiway speed. New wires and plugs, TPS, O2 sensors. I was
getting low voltage and lean on both banks. Changed both O2 sensors and
now am getting lean on both banks. Any help would be greatly appreciated.
Thanks,
Jeff

Re: 94 Explorer giving lean on both banks

My 94 had similar symptoms, and other problems with auto transmission
shifting/lockup. It ended up to be no more than a badly fouled Mass Air
Flow Sensor. I cleaned it and all problems went away. They don't
recommend cleaning, but I have been CAREFULLY cleaning mine every year
or so for 190K miles with only great results. Lots posted on that issue.

Will give it a shot. Not getting any readings on the MAF sensor but I am
getting at the end of my rope so I'll try it.
Thanks,
Jeff

Easy to do, if you need pics and links. Carbon carb spray, a cue tip and a
gentle wipe with kleenex and walla!

Thanks that fixed it. All I went thorough and it was only a nickels worth
of carb cleaner and some compressed air.
Thanks for the help,
Jeff

Great. It's nice to know it worked out for you. By the way, I use a
small artists brush and non residual cleaner like throttle body
cleaner. Have a great weekend. Craig

Re: 94 Explorer giving lean on both banks

The screws holding the MAF sensor are 'Tamper Proof' (also called
'Security') Torx. There is a pin in the center of the star-shaped socket,
requiring a T20 bit with a center hole. You should be able to find a set of
those for about $10 in many auto stores. In a pinch, you can grab the heads
with locking pliers or cut a slot for a screwdriver through the center with
a hacksaw, then and replace the screws with regular ones when you are done
cleaning the sensor (they are metric, but I don't recall the size). Your MAF
will no longer be 'secure', but there is probably no need to worry about
voiding the warranty on a '94 model...

Does it make any difference on the fuel economy?
