Hi,

I guess the mechanic at the Dealership does have that knowledge,
however my own mechanic did not look at any manual.

Did any of the mechanics that could not fix your problem look at the
1997 shop manual for misfire diagnostics?

Hi Folks,

My 97 Ford Taurus GL 3.0 SHO, 130K Mileage  has turned into a nighmare
for the last 4 months.

It shows the following symptoms, I call it the "sad repeating story", I
will refer to this story quite often below.

It starts well, drives well for about 5-8 miles and then starts to show
loss of power, meaning that the car slows down and when I push the
acelerator , the rpm does not go up and the car sort of jerks and
barely goes ahead. I  stop the car , turn it off and turn it back up
and it drives well for another couple of miles and repeats the process.

If I allow it to cool down it drives well for a bit starts the cycle
all over again.

When all of this started in August and I took it to my &#@$% mechanic
who said that the Tranny is dying and asked me to fix it now than be
sorry later, I stupidly did not take a second opinion and had the
Tranny fully rebuilt.

Guess what happend after rebuilding the transmission  the "sad
repeating story" above repeated itself, I then had it checked at
another mechanic and he said that one of the Catalytic Convertor was
clogged.

1) I then had the Catalytic Convertors Replaced, by now I had spent
more on the car than what the car was worth!

This time it ran well for a couple of weeks and then guess what "sad
repeating story" again !!

this time I took it to the Dealership to check for the error codes and
real reason behind my Service Engine Soon Light ? ( Showed Cylinder 5
Misfire )

The Dealership said very confidently that it was just the fuel pump

2) I had the fuel pump replaced and it drove well for a week and then
the "sad repeating story" again !! ( part of the whole story is that I
dont drive a whole lot, work is like 5 minutes from home and everything
else is closeby )

I then took it back to the dealership, had them run diagnostics with
the same - Cylinder 5 Misfire

This time they recommended the following

a) Replace O2 Sensor in Bank One
b) Tune Up ( Said one plug was malfunctioning )
c) Clean EGR ports
d) reprogram CPU
e) Clean fuel Injectors ( they said that it was not necessary )

I had the following done at my mechanic

3) Clean EGR Ports
4) Replaced O2 Sensor in Bank One
5) Replaced all Plugs and wires - Complete Tune Up

The problem did not go away after these three were done, I drove for a
day and was part of the "sad repeating story" again !!

I then

6) Replaced Ignition Coils
7) Repalced EGR Sensor
8) Replaced EGR Vaccum Solenoid

and within 15 minute sof driving after that the "sad repeating story"
played itself again.

I dont know what to do now, the Error codes read Cylinder 5 Misire and
Cylinder 6 misfire.
Please Advise.
