I have a 97 240 with dc sports headers that delete the cat so obviously I'm gonna have a CEL but how do I turn it off I heard about spark plug anti fouler which is rele cheap but I heard that it might not work and I was also told to find out the resistance of the 2nd o2 sensor (which would be after the cat) and then I would get a resistor and wire it in but I can't find the resistance of the second o2 sensor and idk the resistance that it has now with the cat being deleted and all so what should I do?!
