Bad wet start is almost always an electrical issue. Anything ignition-related should be checked first - spark plug wires, coil, igniter and connections throughout. Check the sparkplugs, too - while not the problem, they may contribute due to incorrect gap or whatnot.
Then it might be some other electrical gremlin, having to do with failing sensors or not so good wiring from them (TPS, cam & crank position, knock, MAF). Check, clean (use dielectric grease on connectors where needed), reinstall.
Finally, weak alternator and/or battery may also be contributing to the problem.
