(This
Ford TFI Module is located on the front of the radiator core support on
a 1988 Cougar with the 3.8 V6.)
What
is the problem with the modules?
Due
to excessive heat from the engine, the module has been known to stop
working or intermittently work, resulting in stalling or cutting out of
power to the vehicle's ignition system. This situation has been known to
cause stalling and accidents.
What
Ford vehicles are affected by this problem?
Any
Ford vehicle with the EEC-IV engine system, from late-1983 through the
mid-1990's, has a TFI spark module, including Cougars and Thunderbirds.
Pre-1983 vehicles do not have this module. Vehicles with DIS (distributorless
ignition system) also do not have a spark module.
Is
Ford recalling cars because of the TFI modules?
As
of right now, there is no recall from Ford. However, as pressure
increases on Ford due to the Firestone tire situation, there may be some
type of action. Technically a federally-mandated (government) recall can
only go back 7 model years. During the mid-1990's, Ford redesigned the
ignition systems on engines so that they didn't need a TFI module.
Therefore, not many cars would be recalled if Ford was prompted by the
government. HOWEVER, if Ford is either
responsible enough or is pressured from external sources, they MAY
voluntarily recall all affected vehicles. Recently Ford recalled all
vehicles from 1994-up with the 3.8 V6 for head gasket replacement.
Similar action has taken place for 1994-95 vehicles with the cracking
plastic intake on 4.6 V8 motors. Keep in mind that Ford Motor Company
absolutely does NOT have to recall any
vehicles if it feels that the problem is not serious enough.
However,
there is no precedent for a statewide recall notice through a court. As
of Wednesday, October 11, 2000, a California judge has ordered Ford to
recall 1.2 million vehicles in California only with the TFI modules in
question. The judge was hearing a class-action lawsuit filed by Ford
vehicle owners in the state. The list of cars affected is below:

Ford
is appealing the case, so it may not be resolved for quite some time.
There are also similar class-action lawsuits pending in several other
states. Depending upon the final outcome of the California case, it may
be years until the problem is fully resolved.
In
the meantime, I'm concerned. What should I do with my vehicle?
If
you are concerned about your car's TFI module, the first thing you
should do is have a qualified mechanic inspect it physically. This
requires removal with a special tool. There are two Torx screws sunk
into the module that hold it to the distributor (or heat sink). Once
they are removed, the module unsnaps from its base, and then the wiring
harness can be unhooked. On the top (grey) side is an inspection cover,
under which is the thick film. There should be no seepage of film, nor
should the film be dried up. Also, the plastic around the mounting
screws should not be cracked at all. ANY cracks will allow the module to
pull away from its base, cutting out power and possibly hampering
ignition. The module's halves should be flush and fitted tightly against
one another. There should be no brownish discoloration at the harness
end. Finally, there should be a generous spattering of dielectric grease
(clear or white in color) on the metal backside of the module. This is
to help promote electrical conductivity with the base. Upon replacement,
the old grease should be wiped off and a new fresh coat applied,
approximately 1/32 of an inch thick. Be sure to inspect all wiring
around the module to make sure there are no breaks or pinholes that may
short out the system. In an electrical test with an ohmmeter, the TFI
module should be below 800 ohms or over 975 ohms. If the module falls
between 800 and 975 ohms, it must be replaced.
Can
I replace the part myself?
If
you feel that you can do this yourself, the tool to remove the module is
only a few dollars at any good auto parts store (Auto Zone, NAPA, All
Pro, etc.). Be sure to disconnect the vehicle's
battery before attempting to remove this or any other electrical
component of the car. Use a name brand (Wells, Motorcraft, etc.) to
be sure you are getting a quality TFI module. The cost of the part
itself should be anywhere from $15 - $50 U.S. for your vehicle. Keep in
mind that there is no guarantee that the new part will be assembled
better, or less prone to the problem, than the old module. However, a
new module will at the very least provide more accurate information to
the computer and is very inexpensive insurance.
Owners
of vehicles with the TFI modules mounted on the radiator core probably
will not have any problems with excessive heat affecting the module.
This is because of a large heat sink (dissipator) around the module
itself, and the cooling effect of incoming air as you drive. However, it
is still recommended that you have it inspected for other problems
mentioned above.
