SOURCE: '02 accent GS misfiring & O2 sensor slow response

HI first off the O2 slow resp code is an exhaust leak and not the O2 sensors itself. Slow resp codes is due to to the O2 reading 2 much oxygen or to little exhaust caused by a leak. Now on to the more important. first thing you should do is go buy a can of starter fluid or 2+2 gum cutter and spray it near the injector number one if the intake gasket is or the injector is leaking the car will sputter than run ok for about a second and then start miss fireing again. Dont buy a coil yet. Try this. get a plastic spray bottle and fill it with alittle luquid soap and the rest water. spray the coil pack and look and listen if you hear a clicking noise or a a blue sparking arking off of the coil, also do tis with a your spark plug wires. One last thing if your spark plugs are not ngk thay are wrong and that also maybe part of your problem.
