Hi

First time on the forum - hope my problem is cleary layed out !

My mercedes benz c200 1996 ignition coil seems to be faulty - we have a 'back spark' - that is cylinder 4 is sparking at the coil not the plug - as the car idles , you can hear a 'ticking' at the coil that is under the manifold ( there are two of them) .As you accelerate the car misses badly.

The leads are fine and we put new plugs in which has led us to the coil.

Hope my explanation makes sense !

Keep well

Michael
