Subject: Rough Idle - Ranger 4.0L

About 8,000 miles ago (59,000 on the truck currently), I noticed that
the
idle on my '94 Splash 4.0L was beginning to get a bit rough. At the
exhaust outlet it almost sounds like a miss of sorts - every two to
four
seconds it will sort of 'puff'. At about the same time, the
temperature
gauge begin to cycle from midway to very near the bottom of the gauge.

I took it to the dealership and they told me that this was pretty
typical
for a truck with this many miles on it that was almost four years old
-
which I expected them to say.

Does anyone have any ideas as to what could be causing the rough idle
problem, and, could the fluctuating temperature be related, or is it
just a
coincidence?

I haven't gotten into this (or these) problems much yet, since they
don't
seem to affect the performance or mileage of the truck, although both
problems seem to be getting more pronounced. Figured it high time to
diagnose this one before I have a serious problem on my hands.

Recently, I replaced (as general maintenance) the O2 sensors, PCV,
plugs,
plug wires, & air filter.

Any help would be greatly appreciated.

Thanks,

Eric S. - '94 Splash 4x4 4.0L

------------------------------

Eric,
had a similar problem with my 91 4.0 except that the rough idle and
temperature readings did not occur at the same time. The temperature
reading was a bad temp sensor. The rough idle was clogged or dirty
injectors. I had the injectors professional cleaned where they
disconnect the fuel line from the fuel rail and run it off a
pressurized tank with injector cleaner. Cost was around $70. You can
now hardly hear it idling it so smooth. Hope this helps.

Eric S. with the 94 4.0L Ranger--

I have a 92 Explorer that has developed a similar rough idle. It also seems
to lose coolant, a bad sign, I know. Fuel economy is in the toilet, about 14
at best around town. I have a feeling it might be the old troubled head or
head gasket known to develop in these 4.0Ls. You might want to check your
fuel economy and coolant if you haven't already. I also sense a bit of a
"sweet" (read antifreeze) odor when the truck is first started at times. I
have yet to get it looked at, but will soon.

Subject: F-250/F-350 XLT bench seat

List members,

I have a 1997 F-350 4x4 pickup that I bought in late December of last year.
About 2 months ago, I had the foam in the XLT bench seat replaced because the
wire spring was cutting into it on the corner portion of the driver's side of
the seat. I do not hop in and out of the truck like a cowboy, but as you
know the truck is tall and I do have to hoist myself up a bit to get in, so
I'm sure I slide on it a little bit. Unfortunately, I again noticed little
bits of foam underneath the seat today and sure enough--the spring is cutting
it again. Has anyone else had this problem? I can't believe that I am
abusing the seat this much by getting in and out to cause the foam to
deteriorate so quickly. I am starting to suspect that maybe the spring is
not properly tensioned or that there is something else at fault. I don't
know how many more seats Ford will replace before they start blaming me.

Thanks in advance for any help,
Todd

Try filling the empty cavities of your vehicles with a product called "Great
Stuff" it should be sold in the home repair area at Wal-mart for about $3
per can. I have a 78 f-150 and was trying to hold the noise from the stereo
inside the cab. I used one can to fill the cab corners from the bottom of
the cab to the strike plate for the door latch. It is a foaming insulation
and it hold sound in/out well. Just another thought....

Danger!

2 points:

1) Be _VERY_ sure the foam you pick is not hydrophillic! Some of them
will attract and HOLD water as well as a sponge. You may have speedy
rust forming there soon... hmmm... weak metal doesn't reverberate
so much so _maybe_ rusted out metal is what you want [sarcasm off]

2) Parts of the inner structure of your car may be empty for a reason -
like pathways for escape of condensation, water channels, etc... you
risk doing very real damage to your car by just spraying the foam
in _just_ anywhere. Use your brain, please.

Don't ask how I know... there is an 85 Toyota Tercel in the
Philladelphia junkyard with 4-5 cans of that stuff in it...
fatal dosage... internal rust is kinda bad for an unibody car :-)

Take care.

I have a 93 xcab without the pad for the rear seat headrest. I
noticed on the newer xcabs they had one. Does anyone know where I
could get a red one? Ford wants an arm and a leg of course.
Thanks in advance!

If it were a simple matter of replacing masses of gases of different
temperatures, you'd be right. But there's a lot going on in the
combustion chamber besides swapping gases.Injecting a small amount of
exhaust gas has the effect of cooling the *combustion* process, keeping
NOx formations down, and, at the same time, slowing the flame front,
reducing knock. The whole engine system is calibrated using this EGR as
part of the system; if you remove it, the computer will alter fuel flow
and spark timing, but the compression ratio and cam profile remain the
same. It's a crap shoot as to whether or not you introduce a significant
knock into the engine.
Altering one part of a complex system like a modern auto engine can have
results you never intended (or wanted!).

I don't think that's true.
I think you need a way to prevent cold air from hitting the hot valves,
which means you need some sort of exhaust pipe to hold in some hot
exhaust.
I can't think of a way no back pressure itself can damage an exhaust
> valve.

Actually, a properly designed megaphone exhaust system will run
*negative* exhaust pressure, and these are still used in some motorcycle
race classes.A properly designed scavageing exhaust collector's sole
purpose is to use exhaust pulses to pull the exhaust from the other
pipes in the system, anso introducing negative pressures (look at a
4-cylinder motorcycle's 4-into-1 exhaust system, and see how the
collector is designed to rotate the exhaust pulses in a circular pattern
to pull the exhaust from the prior-firing cylinder pipe).
It's the cold air that can damage the exhaust valve, not a lack of
backpressure.
