<SIGH>... Glad to see that you automatically KNOW you are getting the
run-around. You're car is an extremely complicated electronic device and
intermittent problems occur. If it ain't gonna act broken, what on earth is
someone going to fix? If the information you are giving your dealer is
anything like the information you have posted here, there is little wonder
you are not finding any satisfaction.

If the noise at idle is constant, make sure that it is listed on the work
order as one of your concerns. We are not supposed to upsell warranty. Fords
position is that if you don't complain about it, it isn't bothering you and
if it isn't bothering you they wont fix it. If the noise at idle is
intermittent, make sure that you supply the tech with enough information so
that he/she can recreate the problem... remember that your car is the single
most complicated device you will encounter in your life. Ditto the CEL
(check engine light).... without knowing what code(s) is being set, I can
offer little advice nor can I offer any diagnostic opinions.

I can't speak for other dealerships... ours tries to be sure that we form
some sort of continuity with a vehicle... that is, if I am the first to work
on a new vehicle, they try their utmost to assign any subsequent repairs on
that vehicle to me... doesn't always work out but if I am familiar with the
vehicle, it can help with diagnosing any concerns. Additionally, I know
nothing of your dealer nor their techs... whether they are availing
themselves of the resources tha manufacturer has supplied them... the
technical hotline is not the magic bullet some seem to imagine but they can
usually offer up something that should help a semi-talented tech find the
right track. For some repeat concerns that are difficult to recreate, I have
been known to replace the most likely component - bear in mind that this has
been known to backfire on techs.... how do you spell CHARGEBACK?

Bottom line.... when you take your car in for service, supply the dealership
with enough information that will allow them to recreate your concern(s).
Like I said, if it ain't going to act broken we can't act like we're fixing
it. Be courteous dealing with the dealerships staff... these people are
human beings... they are doing their best to serve you at a time when you
may be frustrated or distraught..... they didn't build the damned thing and
they certainly didn't break it..... the staff that deals with the public
have a very stressful job and if you give them attitude, you will likely get
attitude right back. Like any other business there are good places to deal
and places we don't like. If you don't like the place you are dealing with,
find a place that you do like. Even bad employees would like to fix your
problem and I don't know of anyone (other than government employees) that
can hope to get paid by offering "the run around" as a service.

HTH

Oh, yeah..... some codes would help if I am to offer any diagnostic
advice..... As for the noise at idle, I can only say that your 2000 should
have the updated tensioner for the timing chain. A little more info about
what happens when we rev the motor, if it happens cold/hot/all the time,
service history, type and weight of motor oil *might* help...
