- I have an 89 3.0 V6 Ford Taurus, and I am wondering
- if other owners out there have had a similar experience.
- The car starts fine, but it has a stalling problem that no one
- seems to be able to diagnose. I did a complete tune up, then
- I took it to a highly qualified shop but they cannot find
- the problem unless it is "acting up" as they call it.
- "Acting up", is when I go on long trips, especially in the mountains
- (I live at 5000 ft above sea level), and when the temperature
- is high (not the engine temp, the ambiant temp), then my car
- for some reason starts to gradually lose power, and then
- stalls completely and I have to wait by the side of the road for
- a half-hour or more for the car temp to cool down before it
- would start again. (the engine temperature gauge would have to go
- from a the middle of the indicator- still well within the "normal"
- range- to about the quarter indicator range).
- When the technicians hooked it up to the diagnostic machine
- all fuel pressure coming out of the fuel pump tested fine,
- but the buzz coming out of there was a little louder than ususal.
- Everything in the car tests at the regular settings, because
- when I go to the shop, I cannot recreate the conditions under
- which my car fails and the mechanics say they cannot help on
- intermittent problems unless the problem manifests itself when
- they are testing it.
- My questions are, what is the best way to diagnose such an intermittent
- problem, and if it is not possible to diagnose it for sure has
- anyone else had a similar experience (especially on a Taurus),
- and is it a good idea to go ahead and replace the fuel pump
- and take a risk that the problem would be solved (keep in mind
- that that gamble is going to be costly) ???
-
- Thanks for all your opinions,
-
- Basil
