I just bought a '95 Taurus wagon. Runs fine, although I bought
it because I thought it would get better gas milage than my Jeep.
Seems like it idles fast, too..
HOT 1000RPM in neutral?
15~16MPG? This is a 3.0 liter.
Are these out of the ordinary?
The Jeep, 4.0 liter BOX shaped thing actually gets slightly better
milage.. And is loaded also. Laredo.
I was thinking maybe O2 sensors (2 of them on the Taurus) but maybe
simpler... Is there a temp sensor that is separate from the temp
gauge that might be saying the engine is still cold? (higher idle -
And if I may ask, what kind of milage should I expect?
Thanks for any help!
M y 3.0 wagon gets 16/19 in town. Depends on the conditions.
When its cold, its much worse. I have got as good as 29 MPG
on the road with it.
The gauge temp has a separate sensor from the computer water temp
You need to go through the usually list of suspects.
Clean out Idle control valve assembly.
Clean out the throttle butterfly
Clean off the MAF sensor.
New fuel filter and plug wires.
Check all small vacuum hoses for cracks or leaks.
Replacing the O2 sensors is not a bad idea, but there not
The 3.0 wagon is a little on the under powered side. But its
Thanks for the reply! OK. This might be getting about 'that'
kind of milage. Actually, she's a crossing guard so she's idling the
car for LONG periods. One of the things I've done was clean the idle
control valve. It's clean, and when I remove the power, the idle speed
drops WAY low, telling me it's the computer telling it to speed up. It
idles a bit faster when cold.
I can feel the throttle a bit sticky on the closed side.. I do
need to clean that. I haven't checked the MAP sensor. Wouldn't that
light the 'engine' light or make it run bad?
Do you know where the temp-sensor for the computer is? If I can
fool the computer into making it think it's hot, and the idle then
does drop, I'd assume the sensor is bad..
Thanks for the help!
A couple things I'd add. First, the best initial investment you can make is
to go get a repair manual. The Haynes manual uses pics from the 3.0 Vulcan
Secondly, I'd definitely check the air filter. I've found that some of the
newer autos are very sensitive in this area. I had a Ranger 4x2 4.0 that
liked air filter changes every 10k miles. The filter hardly looked dirty,
but it would make a 3 mpg difference.
Lastly, I've noticed, even tho I'm a Ford fan, that the Chebbys seem to get
better fuel economy on nearly every engine comparision of similar
displacement. I'm not sure 18 mpg is unreasonable for city driving. I have
the newer, more powerful Duratec 3.0 DOHC in my Taurus wagon and still get
about 19 mpg city. I get 26 or so on the highway.
Thanks! We take this car to Jiffy Lube and let them do their
thing every 3k. I've never noticed any changes after the filter had
been changed.. I've been thinking, if the O2 sensor's voltage is
around a half-volt, the mixture is about as stoichiometric as it can
get, and the timing is right, I'd be satisfied, but the 1,000 RPM
shifts into drive and reverse can't be doing the CV's any good.
I've been hunting for the service manual for this car.. I think
there is one just for the drive train. I hope this includes
