Hey guys. All of the sudden today, my engine started running rough like it is missing and the check engine light came on. I took it to autozone and got a P0303 error (misfire on cylinder 3). I replaced the spark plug on 3 as well as the ignition coil. I check the compression and got 165 psi. I swapped fuel injectors with cylinder 2. But I'm still getting the P0303 (misfire on cylinder 3) error. Any ideas?
