My exhausts really has a strong smell, but the smoke from the exhaust pipe leaves a black residue on snow. after running a while pipe raddles. so we believed it was the catalytic converter was bad so we took it off. It ran alright for a bit stared raddling again. still black smoke. bought 02 sensor, after installing it what should I do if problem continues?
