My girlfriends Focus somethings misfires/hesatates slightly when accelarating. It only does it for about a second then its fine and drives without problems.

I've done a bit of searching around the net and quite a few places say it could be the coil pack.

The part number of the coil pack on the Focus is 988F12029AB

Now my sister has recently broke her old mondeo 1.8 and we kept the coil pack off of that. The part number of that one is 988F12029AC.

Would the coil pack off the mondeo work on my girlfriends focus?
