    Hi all, I know this has been covered many times. Here's whats wrong, I've swapped the factory Cats with aftermarket Cats and disconnected the 2 little ECUs and last weekend after a 40min drive in 30c heat the light came on and I can smell fuel. Anyone experience this and how can I fix this?

    It's early, and I've only had 2 Diet Cokes... but here's my armchair opinion:

    stop driving.


    If you have replaced cats, and cat ECU's and you're still getting a slow-down light with the smell of fuel, something is quite wrong in the fuel load on the 1/4 bank.

    Check the connections on both Mass Air Flow Sensors, then check the O2 sensors, especially the O2 sensors. Make sure that they are clean and connected properly, and the the wires are in good shape. Be sure to look under the little rubbers boots that cover the back of the connectors. After you do that you should pull the ecu codes. Run a search of the archives on how to pull them.
