I have used the finned gadget on my Escort for a while.  It is supposed to
lower the temperature of the oil by 18 degrees.  It helped but that wasn't
the problem.  The Escort does a lot better now that the Catalytic converter
was replaced.

Also, on the AFM capacitor fix (which I just did this weekend), the positive
end of the capacitor goes to pin two on the AFM connector or wire.  The
negative lead goes to pin four.  That is the polarity that the ECM sends to
the sensor.  The level is 5 Volts which is in the range of normal logic
levels for TTL and Cmos circuits.  Many Cmos circuits used to run at 12
volts but they then had to be interfaced to other circuits that were 5
Volts.  Also, many of the present computers used for autos are also 5 Volts.
Only the newer super fast computers are in the 3.3 Volt range and that is to
keep the power and heat down.
