What should i do to solve a misfire problem on cylinder 4. Plugs have been changed. I replaced #4 plug, same problem
I have a skip on the #4 cylinder after changing the crankcase sensor. I removed the balance bolt with engine power and disconnected a couple of plugs to prevent the engine from starting.

have you tried checking the coil pack and wires? you most likely have a bad wire or coil firing for that cylinder
I purchased some wires today, changed that wire, now i'm ready to outrun the state patrol. IT WAS THAT WIRE, THANK GOODNESS
That's great. Glad you got it. Drive safe
always the little things in life ^.^
I have a 1996 Buick LeSabre 3800 motor and it's misfiring on num.5 cylinder. I changed the coil and spark plug wire still doing the same thing... Wants to die at a light and or rough idling etc....And I changed the fuel solenoid what's my next resolvement .......
have you tried puting in a new spark plug? they can some times foul out after 60,000 km of use.
