Tourus: Stutter when accelerate

Have a 2002 Ford Taurus, 6cyl. 98k miles. Runs great except when I try to accelerate the motor stutters or when going up long hills, it should kick into a lower gear but doesn't. Plus, when turning left from a stop and I really step on the gas to make a quick left, it also studders and almost stalls. In the latter, the engine light flashes for a bout 3 minutes and then goes off. Thoughts?

sounds like the engine is missing probably do to a secondary ignition problem, like plug wires or spark plugs or possibly coil.
you should have the codes read its probably a misfire code and should atleast tell you or whoever repairs the car what cylinder or cylinders is missing.

Have you tried to manually downshift it into 2nd gear to see if it runs smooth and powerful then, when going up a hill?

You could be dealing with transmission issue, motor mounts, lack of gas issue, or lack of correct spark ignition/timing, or drag on car from stuck brake caliper or clogged catalytic converter - are some things that come to mind.

See how the car coasts to rule out the drag from brakes.

The code on a 2003 i worked on said misfire on #5. it was doing the same thing, loosing serious power going up a hill. Since the intake had to come off to change wires, I went ahead and changed the plugs and wire. Don't put the cheap plugs eaither. The good ones are around 5 to 8 bucks each.
