I've got a '91 Ford Taurus (V6 3.0L) that has always run great and
served me well. But in the last few weeks, it won't run properly in
the mornings. It cranks fine and starts nicely, but will not idle. If
gas is applied, it runs fine. If I drive it for a distance, it seems
to warm up and will then idle no problem. When its warm or has gas
applied, it runs perfectly, very smooth and clean.
It's been suggested that perhaps my temperature sensor is not
functioning (transmitting that the engine is warm when it's actually
cold), and hence the computer is sending a mixture that will not
properly run on a cold engine. This may also explain why my
temperature gauge is not always accurate (sometimes jumps around,
usually just stays all the way "cold").
This is getting to be a real pain. I am still able to drive it cold,
but when I stop at lights etc. it stalls... not good in the middle of
an intersection. When it stalls, the battery warning light and check
engine indicator come on... If I scan the codes on the computer, is
this likely to yield any results?
I've purchased a new temperature sensor for $6, but can't find where I
need to change it from, and I don't have any fancy repair manuals.
Either way, is this likely to fix the problem?
Thanks for any help you can provide!!!
