i have a 1996 jetta gls with the 2.0l sohc engiine , the car was miss fireing on cylinders 1 & 4 so i changed the spark plus and wires hoping that would solve my problem . i used bosch fusion plugs and hi temp wires , now it still misses but i also losing power , the only thing that i can think is it has to be the fuel delivery system , and sugestions would help greatly
