before i get burned for this is checked the sticky how to-spark plugs and it didnt answer my question, i also searched but alot of the threads are out dated and dont work.

all i want to know is how tight do the spark plugs need to be on a 2003 Maxima. how many ft-lb's. i recently put new ones in and im getting a P0300 code (multiple miss fire code)

any help would be great thanks

 

i doubt it has anything to do with your spark plug torque specs.

Did you check the gaps on the plugs you installed?

i would also check out all the connections on your coil packs

oh and the torque specs are 14-22 ft-lbs
