my mom has a cadillac esv and her catalytic converter went out. what will happen? how long do i have to fix it? and will it hurt the car even more to drive while its broken?|||MOST PEOPLE do not know when a catalytic converter breaks, so what is it that makes you think this, if it is an engine light, it could be an internal engine problem, that was picked up in the oxy sensor in the cat, or did you like run over something and break it? this needs to be repaired as soon as possible as the car was designed to run with one in working condition. take it to a muffler shop and have one installed, it takes about an hour, probably less.|||It will fail an emissions test. The CC has no other effect on vehicle function than to 'clean' (convert some harmful molecules into less dangerous ones) the exhaust before it exits the vehicle.
Unfortunately, you will likely have to take it to a muffler shop to get this changed as they are designed to be 'irremovable' in order to deter tampering.|||when your cat goes out the check engine light will come On. Your gas mileage will suffer.....yeah you can drive it but fix it as soon as you can to get better mileage and avoid the rotten egg smell
