Hello and welcome to Justanswer. My name isXXXXX am a Automotive Mechanic here to help you with your problem.

Only getting code P0302 the next step is to check the injector it could be faulty or have a bad electrical connection. If the problem doesnt move when you change the injector position and you can install a noid light to verify its getting proper signal than checking compression is the next thing to do it can be low compression or sticking valve. I would start with that injector right away.

Let me know if you have any qurstions. Thanks
