Compression test? No check engine light?

@CAM

Do you know specifically which cylinder is misfiring?

That is the starting point

Like @mleich said, I would recommend doing a compression test, to rule out a base engine problem

I’m surprised your mechanic hasn’t considered a possible fuel problem. I’ve fixed plenty of misfires due to bad injectors. Some were plugged, others had an open circuit

Uh oh. A Ford 3.8 with a miss on cylinder #4 and slow coolant pressure test leak? I’d pull the #4 plug, if it has any sign of coolant contamination then leave the plug out, pressurize the cooling system and go to lunch. I’ll bet half an hour later there will be slight coolant in that cylinder.
