I have an Actron CP9110 scanner. This device will allow you to view
live data being fed to
and leaving the computer. It will perform features such as cylinder
balance check, wiggle test,
relay switch testing and more. It has a record feature that will allow
you to store data from the ECM.
This is beneficial when tracking down intermittent problems. The
cartridge I have is the CP9112 which
is for 84-95 Fords. To answer your question, Yes there is something
better than a code reader for pre 1996

You can find more information out about this unit at,
look under sunpro.
I purchased my scantool from summit autoracing, their prices were the
lowest around. The scan tool ran
$195.00, the ford cartridge was $95.00. The price seems alittle high,
but you can upgrade to the OBD-II cartridge when
you purchase a new vehicle.

David, I've seen the device you're talking about on a TNN show called
Shadetree Mechanic and it does look sharp. However, what are the
for those of use that have an older vehicle? Is there something besides
code reader or is a code reader as good as it gets?

Don't be too certain of that. Of course 4 low isn't going to take you very
far very fast. It depends on the design of the transfer case. In fact, a
locking transfercase (no diff) will have few problems running engaged if you
are just going down the highway. This is because any difference in
rotational speed is usually scrubbed off at the tires (poor tire wear) as
the weakest link. Yes, you do stress the transfercase when going around
corners, and tight corners are a real no-no, but you can drive on dry
pavement and avoid a "RUINED" transfer case in 4 high if you are careful.

Aside from the increased possibility for mechanical damage, the biggest
reason not to use 4high in dry weather is the unpredictable/unexpected
handling aspects the vehicle takes on. It will now behave in ways that
would be unexpected (as the front and rear are now coupled) and cornering,
braking, and crash avoidance behaviors are drastically different.

That said, it still isn't a recommended practice. The only time I have done
it is when I lost my rear driveshaft on the highway. Put it into 4 high
locked, lock the front hubs, and drove home.

Those with a Diff are more likely to see failure if you get stuck and sit
there spinning the wheels. Unless it's a locking diff, all the power will
be sent to the end of the vehicle without the traction, which causes the
differential to spin rapidly. Sustained power transfer through the diff
like that can cause it to heat up and cause bearings to fail.

I know if I was building a 4x4 from scratch I would use a viscous coupling
for the center transfer case. Great for full time 4x4 systems for many
Smooth power transfer
Acts as a differential at low rotational differentials (parking,
curves on the highway)
Acts as a locker when high differentials occur
Can handle tons of power
Relatively light weight
If I ever go full boar with my 2.9 Ranger and try to get more than 200hp out
of it, I may have to investigate such a unit.

If the "creator" of teflon says its not for engine oil, that's enough for me.

However, I think that teflon could be used as a permanent coating on
the engine parts even if it can't be used directly in the lubricant.

Can anyone get me a copy of Ford's TSB on the Explorer vibration problem
above 50 mph? I'd appreciate it.

Somebody posted -------------------------------------------------

For fords, I haven't seen any home built scantools for the older non
systems... There are a bunch for GM's though... Probably the closest
is Diacom.
They make a cable/software for the older GM/Ford/Chrysler vehicles, but
it's $400.00!

For all the pre-OBD-2 Ford computers, you can buy a ready-built
hand-held scanner made by Equus, and I understand sold under another
name or two. It has a digital display and holds a few readings, runs on
(2) plain AA batteries. The unit is Ford-specific. I bought mine for
around $60 from JC Whitney, plus another $20 for an extension cable that
lets you run a few dynamic tests from the driver's seat. It has been
very civilized in use, and I find it well-thought-out. Great to carry
in the vehicle.
I'm surprised I'm the only person who mentions it here; would like to
hear from others who have used one.

It might be a good idea to buy one soon, before they discontinue it. A
lot of places sell their cheap model with the flashing lights on top,
but this item is more expensive and far more useful because it has the
digital readout and holds a few codes in memory. They don't offer a
corresponding model for GM and Chrysler.
