Replaced the spark plugs on my 2019 CX-9 this afternoon - all seemed to go OK but very rough/smelly idle after replacement and flashing CEL. Code reader showed P0303. Tried to reseat all the coils but still getting misfire.
Engine will idle relatively smoothly now but lots of vibration lack of power when in reverse or drive. If I can't clear this up myself is it worth limping it to shop or should I have it towed?
Any suggestions?
