Code 1320 after a new coil on #1 cylinder

Question

Engine was misfiring and I got code P0301. I changed the coil, the P0301 went away. However, the car was still mis firing and now got code P1320. I will change the spark plug, but if that doesn\'t work what would be my next target?

Answer 1

HI there,

You may have to replace all the coils to resolve this code. That is the factory repair. The car may also finally give you a specific cylinder code like it did with cylinder 1. This code basically means the car knows there is a problem but isn't sure which cylinder is causing it.
