2012 CHEVY IMPALA p0303, p0300 part 1

This one is a CLASSIC, costumer complain was misfire all the time. I think coil and plugs were replaced, codes were cleared… I figured it out the misfire was on 3 and swapped coil and plug to other cylinders. Big mess, someone was here for sure… Figured out that misfire was on number 3 cylinder. Did a fuel injector test with scanner and number 3 seems to be bad. Thanks for watching
