Just to let u know that the zetec wires get very hot and the dieletric grease breaks down from heat. You need to buy some greese and gunk alot in there. Talking about the terimals and boots of the spark plug wires and coil......The low end jerking is from miss firing in the wire from the coil, plus make sure there is not heat deteration from the excess jerking and heat..
