I recieved a code p0305, since then i've replaced cap, rotor, plugs, wires and switched fuel injectors from cylinder 5 to 2. I did a compression test and all cylinders range from 105 to 112. I recently took to local dodge dealer and they replaced the pcm, 50 miles later the engine light came back on and code p0305 is back. Help!

there's no obvious miss and the plugs look normal, just did a fuel pressure test, and is 48 to 49 psi

The only thing I can think of is a weak coil (if you can't feel the miss). However, I would think you would find other cylenders missing too. You already tried switching the injectors which did nothing. Have you checked the wiring to the injector and where it plugs into?

If you can't feel a miss, and everything checks out good, I would say take it back to the dealer that replaced the pcm. Something is up with the wiring to it to continue setting the same code.
