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
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.
