I was going to originally post this in alt.autos.ford.escort but when
I saw the amount of SPAM and nearly zero activity... I thought I'd
pose my question(s) here. Hopefully someone here can shed some light
on my problem(s).
First off, my subject line pretty much describes my problem. From a
standstill and if having to accelerate briskly... my '97 Escort Wagon
is lacking severe power from 0-35MPH. Once I hit 40MPH the car runs
like a champ with zero hesitation.
Shortly after this symptom developed... a P0303 code fired which
AutoZone told me was a misfire on cylinder #3. I later brought the
vehicle over to a friendly mechanic who hooked his $3K Snap-On
diagnostic tool to the ODB-II connector and ran a suite of tests and
checked every sensor. Every sensor reported within spec.
He then tried the old trick of removing each plug wire individually.
Each removed wire caused the engine to run like crap. He removed the
vacuum hose from the Fuel Pressure Regulator and we heard a sucking
sound so I guess there was proper vacuum. I'm told that if there was
a problem with the Fuel Pressue Regulator gas would pour out from it.
The mechanic then checked every connector on each fuel injector. I
later drove the car in order to "test" it and it still ran like crap.
In checking the plugs it appeared that the #3 plug was half tan and
half (slightly) black. He replaced the plug and the car "seemed" to
run a little better. I couldn't be sure so he took a ride with me.
Seeing he was unable to diagnose my problem he gave me a freebie for
his diagnostic services. This is a guy I need to stick with. :-)
Anyway... when got home I went ahead and changed the other 3 plugs.
Later that afternoon... the car appeared to run normal again. Now,
before anyone thinks it was the plugs let me say that a few days
earlier I poured a bottle of Techron down the tank. Is it possible
that a clogged fuel injector (specifically #3) finally got cleared?
Last week the alternator on this same vehicle went out. Since I had
to disconnect the battery and the computer got cleared... the car has
been running like crap again but this time the lack of acceleration
seems more severe... almost dangerous. A "service engine soon" light
has already appeared and it appears to be firing quite regularly since
every now and then it starts to flash which I believe another code has
fired while one has been previously stored.
Again, going to AutoZone I see that the code is still a P0303, a
misfire on cylinder #3.
I've since bought wires which didn't fix the problem. I bought a coil
pack but haven't installed it yet as I don't want to be throwing darts
at an elusive problem. Correct me if I'm wrong... but my feeling is
that if the coil pack is bad... wouldn't I be getting random cylinder
I'm also convinced that I've got a bad fuel injector. I was thinking
of swapping the #2 and #3 fuel injector to see if the problem follows
the fuel injector by possibly getting a P0302 reading. Good idea?
Last night I dumped another bottle of Techron down the tank. Who
knows... maybe in another day or two this will be a non-issue. :-)
If any of you are still reading this post... thank you for your
I'd appreciate any help in this matter.
