It's hard to say. You can try swapping out injectors between cylinders to see if the misfire tracks the injector or remains with cylinder 1.

I would expect that you would see a Bank 1 misfire error then as well. |

ok, so after checking the injector on cyl 1, I found that it was good. I compared it to the other resistance readings on the other cylinders . all the same. went back to the coil and starting comparing resistance on the other coils. the new coil I put on cyl 1 was bad too. sent it back and ran over to the dealer. bought a new coil and all good. all back to normal. reset codes and driving again. thanks for all the help guys
