Do you mean the cruise shuts off or the engine? Possibly a failing vehicle
speed sensor if it's the cruise, I'd check the ground circuits first if it was
the engine. The brake switch for the EEC system could be faulty as well;
either of these (VSS or BOO) would shut off the cruise control if giving false
readings. Certainly other possibilities as well but this should be a good
start.

Yes, yes and yes. It's amazing the difference it can make in subtle
drivability problems. The coke that builds up on the throttle edges holds the
throttle open slightly beyond the designed amount and also disturbs the
airflow around the throttle. Depending on the system used for cleaning,
carbon will also be removed from the valves and combustion chambers with
further gains in drivability.

Over the years I've used many different cleaning devices and IMHO the way to
go would be a BG product, preferably the 'induction service' that cleans the
whole intake rather than just the injectors and spraying off the crud on the
throttle plate.

Probably not in the owners manual at all but suggestions range from 15K
(especially on the modulars) to 30-50K depending on outside factors.

No guarantee but it *may* help on both counts. With the time and mileage on
your truck the O2 sensor(s) might be getting degraded as well. Don't discount
the on-going changes in gasoline formulation either.

Many thanks to Buck Shoff for some help off list regarding some diesel
questions. Like most of us he's well worth talking to and more than willing
to help another FTE'er. If I could send a case of beer on-line it'd be on the
way to him for his help.

I have a '93 Explorer 4x4 that I noticed was leaking radiator coolant last
week. Upon closer inspection, it looked like it was coming from the water
pump. Well, not wanting to blow my entire Saturday changing it, I took it
to the dealer (I know many of you are saying, "well, that's his first
mistake," but I have to take it there in order for my crummy warranty
company to pay the bill). Now, what looked like a simple water pump problem
to me, the dealer says is a bad thermostat housing (parts on national
back-order)and in the process they've discovered that the intake manifold
gasket needs replacing!?! Total repair bill = $600. The warranty company
will pay most of it, but they won't pay fo replacing the coolant, and a few
other parts (the dealer says they need to put in a new oil filter because
the old one gets screwed up when they change the intake manifold gasket).

Does any of this sound right to you all? It seems like an aweful lot of
money for a seemingly small problem. I think in the end, my out-of-pocket
is going to be about $125...so I'm not really complaining, but it just
sounds fishy to me.

Thanks,
TimR><>

Any time you pull the intake to change the gaskets, you run the risk of
getting coolant and/or "crumbs" into the oil pan... Always a wise idea to
change oil and filter after the intake gaskets are changed, and before the
engine is started again. However, you might want to read the warranty
companies policy on covered items... if they do not have a disclaimer that
states that they do not cover coolant that is required for a warranty
repair of a leaking item, then they have to cover it under federal law...
Bottom line is research before buying a warranty... I'd be leary of any
warranty company (Aftermarket) that requires a dealer to service the
vehicle, and not whichever repair facility you choose.

Niether is uncommon..

You're lucky any of it's covered.

As David mentioned there will be crud involved in the manifold R&R and
generally coolant will get into the oil during the process as well so an oil
change would be SOP after the work.

A second opinion from a trusted shop might be worthwhile depending on the
amount charged to look at it.

Not all but many of the third party warranties seem to be a waste of good
paper and ink... The front side in good sized type lists all it covers and
the back side in tiny type negates everything the front side says. Example:
Front- Engine; oil pump Back- Not covered; lack of lubrication. What happens
when the oil pump fails? Lack of lubrication! I've seen quite a few claims
denied for various weasel worded reasons and a minority of (major) claims
backed. Some for good reason like one we have right now that had less than 16
Oz. of oil in the pan but others were just plain incomprehensible in the logic
for not covering it. (Covering the timing belt but not the bent valves
springs to mind on one with LESS than the mileage suggestion for the belt
replacement.)

Many of the people with ford-trucks.com or ford-trucks.net accounts
are either not checking their mail or in the case of ".com" addresses,
not having their mail software delete the messages after retrieval.

This situation is getting out of control, with half the mail queue
space being taken up by mail 3-9 weeks old. This weekend, I will be
installing software that will delete all mail over 3 weeks old. FTE
