My check engine came out and it reads P1304? How do I fix this one its weird cause my mechanic was telling me its because of the aftermarket distributor I got from autozone thats y but I had to replace it 3 times. And the check engine light once I cleared the codes it usually pops up again after a day or 2 of driiving 40miles and up. Pleae advice me on this cause its giving me a headaches. What I did was replaced the plugs, wires, distributo already.

After checking the cylinder via compression test and checking the injectors via gauge all seems okey. Its just these check engine light is popping up every other day. And even though I erased it it still comes back. What else do I need to check? Ive already replaced all the plugs, wires, distributor check for compression and leaks check the injectors and everything is ok. Is it probably my PCM? Please help thanks

These is the code that keeps popping up like what ive said we've done a compression test and check the injectors too so far both are working. We just run out of ideas weve replaced the plugs the belts and the rotors still it keeps popping up
