2001 Chevrolet Impala Question: spark plug order

i got a code p0304 witch is miss fire from the spark plugs i just replaced all plugs and cords and it is still there what should i look for to know why the plug is not firing properly -
Answer 1
Code P0300 is engine misfires so I am going to say that the P0304 you retrieved is a misfire in cylinder number 4. Check the coil for that cylinder both visually and with a DVOM for the proper resistance. -
