1998 Sunfire 2.2L

Good afternoon everybody. I have a 1998 Sunfire with a 2.2L. Getting codes P0200 and P0302. Car runs terribly. Replaced #2 fuel injector- no improvement. Replaced PCM- still no improvement. Then I spliced into each positive power line for fuel injectors one at a time and gave them direct power from the battery to see if maybe one of them was partially broken or grounding somewhere in the harness. Nothing found. Any ideas???

Forgot to mention, after all that it's still throwing the same codes after clearing.

I did follow those procedures with no luck at finding the problem, so I figured that I'd attack the misfire first. Installed new plugs and plug wires for all cylinders and a new coil pack for #2 & #3 cylinders. Thought that might stop the misfire code, but instead ( believe it or not ) it cleared the injector code. I'm getting the other coil pack tonight because it seems that a bad one can have an effect on more than just the cylinder it's controlling.
