We have a 1996 integra with a after market convertor in the exhaust. Since this was put in the CEL is always on. The O2 sensor down stream of the convertor is a 4 wire sensor. Is there a way to get this CDL to go out. I was told that a resistor placed inline on the 4 wire O2 sensor will make the CEL go out. What size resistor and which wire on the O2 sensor do I use. Thanks for the help
