'99 Taurus - Loud Noise/Vibration on cold start
I have a 1999 Taurus with about 110,000 miles on it. I live in the
northeast US. For the last several months I have been getting a sound
of a loud vibration in the engine of the car. The noise only occurs
when the car is first started and the engine is cold. Generally it will
last for the first five minutes of use - when the car is put into
reverse for the first time; drive for the first time, etc - then it
goes away once the car is warmed up. It seems to be worse as the
temperature drops and tends to be noticeable for a longer period of
time the colder it is.
It only occurs with a cold start. So, it happens in the morning and at
the end of my work day when I am leaving my job. If the car is warmed
up and I go into the store for ten minutes, when the warm car is
restarted, the noise does NOT happen. This noise does not seem to be
affecting any other aspect of the car's operation. It drives,
shifts, and accelerates fine. It is more of an annoyance than anything
else and if I wasn't worried about it waking up my neighbors and my
home owners association lodging a complaint, I might even ignore it.
Had it into my local Ford dealer last week and they suggested flushing
the transmission fluid. That was done but the problem is still there.
Today I brought it in again and they are now telling me they need more
time to look at it and want me to bring it back next Saturday for them
to continue their research. The only thing they could tell me is they
have narrowed it down to the noise coming from either my ABS or inside
Anyone familiar with a loud, cold start, noise that goes away after
five minutes, so I can offer my Ford technician some guidance?
