3L V-6 with about 60,000 miles getting 25MPG always. When cold as in 40 to
50 F the engine may stall and die or when just starting down the road at
about 25-30 MPH it may hesitate then pick up and run fine. No problems when
warm. No indicators on the dash. Dealer charged $65 to look at codes and
replace something called the air bypass idle air control valve. Of course
they tried to sell me a injector cleanout job also which I refused. I took
them a full day to replace that little motor-like device atop the engine and
$195.00 P&L. Two days later it did the same thing during a cold start-up
then settled down and ran fine. Did I screw-up by not having the injectors
cleaned? I've always heard that it was a waste of $.
Injector cleaning is not a waste of dollars. Deposits do build up and
performance may decrease. Most of the gasolines on the market today have
plenty of detergent in them, but given the miles you have it wouldn't hurt.
I would shop around for the best price on the cleaning, and find out exactly
how they do it. If they are removing each injector individually and
cleaning (just about as easy as pulling a spark plug), then I would consider
it. If they are simply dumping a bottle of injector cleaner in the tank,
then I would turn around and leave. You might try buying a bottle of
injector cleaner and follow the directions on the back. I did that for my
80K mile Windstar w/3.8 and it made a difference for me.
Hope this helps.
'98 Sable here. I've never had my injectors cleaned and with 171,600 miles
on mine, it takes off like a spotted ape. But then I'm a firm believer in
getting the lead out when taking off. I don't stomp it, but I don't ease
up to speed, either. I typically accelerate faster than the pack at the
I don't know. In my experience with cars, they seem to run like shit when
I first get them. I don't do much to them beyond normal maintenance, but
after a few months of my driving habits, I swear they run much better.
I think most mechanics will tell you that it's good for a car to get it out
on the highway and blow the soot out of it. And I just never let the soot
build up in mine. Mechanic says the inside of my engine is exceptionally
clean. To me, that means I've been doing something right, so I just keep
on doing it.
The only problem mine does have, and it's had this problem since I've had
it, is a problem with clattering. I have to burn premium. But so far I
haven't taken it in to a Ford dealer for that specific problem. An
independent shop said they never could get it to clatter. I guess I should
have put some regular in there before taking it to them. :-)
