Have you OBD'd it mine had something similar and it shows up as the Heater sensor on exhaust start-up. There's two, left and right sensors trying to get the emissions up to temperature for the engine to settle down on the revs. It also so I'm told has something to do with the Airmass intake sensor which causes it to hunt until its happy with operating temperature.

What about the coils? New? Used? OEM Jag/Motorcraft or aftermarket? If used or aftermarket - get the coils tested.

PS - that coil will need to be replaced and your going to have to seal the windshield cowl.
As a short term fix you could put some hylomar around the coil cover but water will eventually find its way into the spark plug well shorting out the coil.
