Do you wrench? This check is real easy to do.

Each spark plug has its own spark coil. Were the codes P0301 and P0303? The last digit designates the cylinder number.

Open the engine's top cover and mark the coils 1-2-3-4-5 starting at the accessory end (left side as viewed from the front of the car).

Swap coils 1+2. Then swap coils 3+4. A small set screw (10mm) and unplugging is all that's required to remove a coil.

Put the cover back on and drive it. Then check to see if the misfire codes change to P0302 and P0304.

If that happens you have determined the source of your misfires are 2 bad coils.

Let us know what you do about this and how it turns out.
