The car now has 48,500 miles. The car still has original coilpacks as far as I know.

Most recently the problem has been availability. The latest part number (suffix) is L or M. I've had my L parts for 35k miles with no issues. Of course, my originals didn't fail, they were swapped as part of the recall.

good luck and let us know how things work out!

In some cases, the failure results in practically a total loss of the ability to generate a spark at the plug, hence the continuous sputtering you mention. In another common coilpack failure mode, the severity of the degradation of the coilpack internal electrical components is less severe. In these cases, the coilpack fires the spark at the plug gap OK when engine cylinder pressure is comparatively low, but is not able to produce the ignition voltages required to force a spark to jump the plug gap at higher engine loads, when cylinder pressures increase beyond the ignition voltage limited value. (Spark "blow out")
Thus, the engine runs normally with small throttle opening angles, then collapses into misfire as the throttle is opened further.

This helps alot. Thank you very much. That sounds exactly like my problem.

just to let everybody know, It was a coil pack. Thanks for all the help.
