    I've got this code on my car that brings up the eml light. Will this just be a sensor that needs replacing? Or will it involve a remap? As it did have a decat pipe but I've since added and powerflow sports cat to the pipework. I'm hoping to get it back to normal. Also the the new cat stinks of eggy after I've been heavy footed. Normal driving is fine. I don't understand why people want to delete the cat. It does a important job. But if anyone could advise weather to buy a sensor or invetiage if I have a hole somewhere first that would be good. Would a hole make the sensor through up a code and would it make the cat smell like it does? Just trying to figure out what's the best solution to all of this.
