Peugeot 307 anti pollution fault help plzzz » Peugeot 307 forum » Peugeot Central

Hi I've got a 2005 peugeot 307 1.6 Auto, I've got engine management light on and also getting anti pollution fault code displayed in the dash. I changed O2 sensor, cam sensor and the two sensor that are located in the exhaust but the problem is still there. My mechanic switched off the engine management light few times but after couple of days it comes back on, the two codes I get are P0341 'phase detection integ ignition coherence' and P0420 'Ageing Catalyst'. And sometimes it doesn't start ( that only happens when I've driven for a while and switched the car off and it won't start again) and then if I wait for about an hour or so then it starts normal. It's also become really juicy lately. Can anyone help me please because I don't know what else to do. Any helps would be really appreciated.

Peugeot garage could not find the same fault on my 307, i solved it by using Red X in the petrol. i use it regularly to keep the valves clean. its been about 2 years now without the anti pollution symbol showing
