Question about 2008 Ford Taurus Limited
There are no odd noises. Acceleration seems normal at all other times. The sputtering happens between 62 and 65 MPH. No engine light. All seems normal other than stated.
Hi, Sounds like a bad coil or a bad spark plug. Also check for codes on computer. (ECU.)

Check engine light is frequently a loose fuel cap, but the other problem could be a bad fuel pump, or a clogged fuel filter. Try the fuel filter first - its the cheapest.

This is normal. Four cylinder engines do not have a lot of horsepower and torque.
When your a/c compressor and cooling fan kick on, there is a load on your engine that casues rpm to drop. When it kicks off, the load goes away and the rpms go back up.
Your a/c system is the cycling type that increases fuel economy. It should cycle 4 to 7 times/minute at 70 degrees F.
Please rae as fixed if this answers your question.
PS. With the a/c (and defrost) off, it should not drop any rpms.

From what you are describing it appears like an engine misfire.
These trucks are notorious for bad ignition coils.
They don't always set a code either, it depends on several factors.
To check these out in my shop there is a mode in our scan tool called "mode 6". This allows us to look at certain engine data parameters to look at misfire to locate the offending cylinder(s).
Unfortunately without the use of a scan tool you will not be able to see this.
It may be in your best interests to get a shop to look at this for you and verify the bad cylinder.
I have had issues with aftermarket coils and use Ford originals exclusively now. They have also reduced the price of them, good thing too because we go through many.
Might be an opportune time to replace spark plugs as well. worn spark plugs can accelerate coil failure as a worn plug takes more energy to fire.
Thank you for using FixYa !
