Default 2004 Taurus SE running rough when accelerating

Suddenly about two weeks ago my engine started running very roughly, especially when accelerating (particularly around 40-45 mph, when I think it's shifting to the highest gear), but runs smoothly when I maintain a constant speed, even up to 65 mph.

Engine light came on also.

Please help. I must confess when it comes to cars I'm kind of a chick.

Sheila, sorry it took so long to get back.

Here's from the Autozone printout:
-------------------------------------------------------
Troubleshooting: P0352

Definition
Ignition coil primary circuit condition- coil
number 2
Explanation
The ignition coil primary circuit is monitored for
errors.
Probable cause
1.- Ignition coil defective
2.- Secondary ignition-plugs, wires, cap, rotor
3.- Poor electrical connection or circuit fault
4.- Driver circuit fault-ignition module or PCM
--------------------------------------------------------
It generally drives smoothly when I'm maintaining a steady speed, and sputters and lurches sometimes when I accelerate, especially when it's cold or when it's around 45 mph.

Gas mileage has dropped from about 18.8 mpg to 18.1 mpg.

Switching to premium gas has definitely helped, although I realize that's a waste of money.

Any ideas?

Also, how do I determine whether my SE is Vulcan or Duratec?

Thanks in advance,
Bob Waldon

All SE were Vulcan. SEL were Duratec until 2006 (I believe). '06 and '07 all models come as Vulcan only.

Premium is not a waste of money, as it does not contain any ethanol (most of the time, at least in Shell gas in Canada), contains more detergents (read makes your engine cleaner) and gives you more mpg.

I'm not familiar with that code, but I'll assume that somehow the ignition module sees that the coil pack's voltage isn't finding its way to ground. If the plugs and wires have never been changed, do it. Autolite or Motorcraft platinum plugs, and Autolite professional or Motorcraft wires are good. If the code is still present, then the coil pack is probably bad.

Premium fuel IS a waste of money in an engine designed for regular fuel. At least here, ALL grades of fuel contain 10% ethanol (E10). All grades of Tier A fuels have sufficient cleaning agents in them. Premium fuel actually contains LESS energy per gallon than regular grade fuel.

Thank you for your protection and your many signs along the way. Thank you for any good that I may have done, I'm so sorry about the bad. Thank you for the friend I made. Please watch over her as you watched over me. Thank you for finally allowing me to rest. I'm so very tired, but I go now to my rest at peace. I fought the good fight, I finished the race, I kept the faith.

^ Bob, does the engine have spark plug wires, if so a vulcan, if not, a tec in 04. I would check/replace plugs, wires (if you have them) and coil. If you have cop (coil on plug), you may just need to replace #2 coil. #2 cylinder is is middle back (firewall bank).
