P0306 INFINITI -

Question

i have a 2003 infiniti g35 sedan and appear to have the fault code p0306 on cylinder 6.

and i will like to know what could be the best thing to do in order to fix it

right now the car shakes at idle and when its stop shakes too. as i increased the speed the failure seems to go away at high speeds you nearly notice the shake . but once you stop again shakes again and the ride feels rough just when you start the ride . even on reverse shakes too but i don't know what else to do.

i all ready change the 6 spark plugs and the coil on cyl. 6 new oil and filters.

if somebody can help me i would appreciated long time . thanks
