The 4th cylinder is misfiring on my 1996 mercedes benz c240 how do I fix it?
Chance the spark plug first. If that doesn't work, chance the coil pack, if that doesn't fix it, chance the ignition coil for that cylinder. if that doesn't work, it is probably a fuel delivery problem/injector problem.
Instead of buying a bunch of parts that don't need changing, swap the plug with the cylinder next to it. If 4 is still misfiring, swap coils, etc., etc., etc.
That is true! Great advice.
