Have you verified that cam timing is correct or not? I'd start with that. What plug wires are those? The best thing I did for my 2.3T was pick up a set of genuine Motorcraft wires.
Don't neglect the basics. Check fuel pressure, ignition timing, compression, and I would also thinking about a leakdown test to pinpoint any problems in a particular cylinder.
