Did a little research for you.
Most likely causes of P0205 (in no particular order):
- Bad cylinder 5 injector
- Open/short in spark plug wire to cylinder 5
- Bad PCM
You've already ruled out two of the problems by replacing the injector and PCM. Next most likely cause is spark plug wires.
Grab some new spark plug wires. If they've never been replaced, its probably time to do them anyway. Here is the TSB for the wire routing, make sure your wires are properly routed when you install them, as suggested by Ram15002ndGen.
TSB 18-48-98
You can try rerouting your old ones first if you want to, but like I said, if they've never been replaced (or you're unsure when they were last replaced), it may be time to do them anyway. A decent set can be had at O'Reillys for a good price.
