I have a z6 in my crx. modified a/t chip to m/t chip. hooked up 4 wire o2 sensor correctly. the cel light for code 41 went away, then i put a cam gear on it. After that the cel light for o2 would sometimes come on when getting on the engine. Now the cel light is constantly on. and idles kind of bad to. the cam gear was put on when at tdc and i havent changed the setting on it. I am out of ideas.. anything would help! thanks

 

Ever consider the possibility that your new sensor is bad or your wiring has a loose connection?

 

i changed out the o2 sensor yesterday, still nothing. I guess I'll have to run through all the wires tomorrow .. agh.
