I have an odd issue with my car. I have a '97 Ford Taurus that will
start and idle fine when a cold or warm start. Warm being less then say
20 minutes. But if the car has been sitting for about 1/2 hour it gives
me trouble. It will start fine, but then immediately idles rough and
will die. I can restart and it fires right up, but then will die again.
The only way to keep it running is to hit the gas after it starts and
rev the engine up.
If I rev it a little and then let it idle it idles VERY roughly. You
can watch the tach jump around. If left it usually will kill again. So
I usually end up riding the brake and holding down the gas a little
until I can get out on the road to get up to highway speed, etc.
Once on the road it cleans right up and runs fine. The interesting
thing is that I have talked to two other people with similar year cars
and the same engine. I have the 3.0 six cylinder 145 hp engine. I
believe its the Vulcan engine. It is NOT the DOHC came and is not a
flex fuel engine.
If anyone has run into this problem and has found a cure I would
really appreciate hearing from you.
Thanks in advance,
