sooo.. I've got an 04 disco # 2 and 3 misfiring intermittently but more often than not. Got new plugs, magnacored up, replaced coils because of this problem and its still here. I dark tested for arcing and everything was good. The only codes I'm getting are 2 and 3 misfiring. Could this be a CPS problem? I'm at my wits end with this thing.

Thanks,
Richard

 

Bump.
