I have a 2014 Toyota Corolla with 177,872 miles and keep getting codes p0302-p0304 and p0353,p0354. I have already put new spark plugs and I checked the coils and they are fine I even replaced the fuel injectors and I still keep getting these codes. I also replaced the fuel pump, I don’t know what else to do. Help!

How did you check the coils? Did you check for vacuum leaks?
See the following for possible causes:

It sounds like the ECM may be going out, especially with all new OEM?) coil packs. Have you checked all the wiring for corrosion and tight connections?
