You should check your duty cycle and report what it says. Also, can you give a vacuum reading? One at idle, another at 1500rpms or so.

Further more, don't think your injectors are good just because they are not clogged. They can be lettng TOO MUCH fuel at idle causing the misfires, until it can burn it out.

Swapping parts is the most frustrating way to try and fix a car.
