Will a bad O2 sensor always throw a code, or can it be bad and not set it off. I'm trying to narrow down and exhaust smell at high throttle. My son was following me one day doing about 75-80 and he tells me he can really smell the exhaust so I'm searching for the reason. I have diacom software so I guess I'll have to find the voltage to see if thats the problem. I also noticed I'm getting some injector sounds that seem kinds loud. any suggestions ?
