    Catalytic Converter work

    Guest-only advertisement. Register or Log In now!
    I got my catalytic converter cleaned out yesterday, and my car sounds like a cheap car on idle and it smokes on when i start it and drive it. Are these symptoms normal after a catalytic converter cleaning? I also don't have the o2 sensor seals in yet and my CEL light is on. Its an 08 3.2 quattro btw

    If your o2 sensors are not installed properly it will cause issues.

    I didn't do it a tuning shop did. Cause I had misfires. After a carbon cleaning changes 4 injectors, and all spark plugs.

    Make sure the o2 sensors are installed correctly and on the correct banks. Also make sure the intake manifold and injectors are installed correctly. If you have a vacuum leak it will run like poop.

    This is hilarious, did they refill the headlight fluid because I hear that can cause misfires as well.
