Hi, everyone. I had a set of faulty sparkplug wires which caused the car to hesitate and bog when accelerating. I was trying my luck with aircare/emission test with these sparkplug wires and I failed. I replaced the bad wires with a set of good ones. havent tried aircare yet. But can these set of bad sparkplug wires caused me to fail airacre? My car is 93 240sx KA24DE. new Cat installed 2 years ago, and the car runs smooth as silk with no problem at all. I cant smell/see anything comming out of the exhaust physically. lemme know what you guys think. cheers
