    Default 307 2004 SW petrol. Catalytic Error with codes. Any help appreciated.

    Hi fellow frogs.
    I am trying to solve this problem we are having with a 307 SW 2004 petrol auto.
    At start up there is immediate engine light and Catalytic error warning on dash screen.

    The coil pack, plugs and EGR were all changed at a shop in an effort to solve the issue - inital codes were cleared by the mechanic and after driving around for a short while the car was ok. Parked the car and faults have returned.

    I now have the car and trying to help my mate fix the problems.
    The codes i am getting are;

    P0410 - Powertrain Secondary Air Injection System

    P0204 - Powertrain Cyclinder 4 Misfire Detected

    P1340 - Powertrain

    all codes read from Torque app and Bluetooth ODBII adapter.
    Codes cleared but return as soon as the car starts.

    The car when started cold makes a loud noise at the pump which stops after 30secs or less
    The car idles rough like in limp mode or miss fire, when driving there is a huge loss of power.
    Obviously running on 3 cylinders.

    I have removed the main hose from the pump and air is coming from the pump and through the hose
    so no blockages at these 2 points.

    I have checked all the fuses.
    I filled the car with 98 fuel and took it for a drive for 30mins

    What should be my next thing to check here, seeing as we have a new coil pack, plugs and EGR and a working pump?

    thanks for any help

    Donít worry about the air pump fault wonít cause miss .
    I would do or get someone to do a relative compression test first using a oscilloscope not a manual gauge and do it cold and hot that way you can see if you have a problem with the lifters etc if you need more info let me know without doing this you really donít know
