Triple Gran Cherokee na bobina de ignição de 1999

That such a good day, I have problems with my Grand Cherokee Laredo 1999 truck with a 4.0 -cylinder engine online., The problem is that it is pulling, it trembles a lot, this went to root that I change bujias, this engine model does not bring wiring to the spark plug Sparking, as if I were short of the coil, but I already revicts and clean and assure me that everything is perfectly well connected and still sparkled the spark plug, my doubt is whether the A bobina já está avaliada ou pode não ser a apropriada ou você deseja um curta independente e estou impactando isso no sistema de ignição ... ajuda por favor se alguém souber disso, ...
