2002 Vauxhall Zafira fault codes

hi,did you replace all the exhaust or just the cat as sometimes when the cat breaks up the bits collect in the silencer & restricts the flow of gases, sorry dont know what the codes are

yes it was the full system as cat broke up car fine at idle just when you start to move it starts to judder about then dies tryed running it with air filter of works fine till you move
it's like it's not getting enough air or fuel but fuel pressure is fine only had the problems since we had that cold snap

Fault codes,

Hope this helps

are the plugs ok?coilpacks can break down on these engines especially under load?does the engine rev uo smoothly?

yes new plugs and coil pack was working fine until 2 weeks ago engine light cam on car with spanner light never comes on with any of the faults the last time the coil pack went the car & spanner light came on exhaust aways gets very hot right to the back of box the exhaust sound is lumpy and hot after about 10 mins when you start up the car it runs normal till 10 mins of driving

if you can get a diagnostic done on it,you need to check the live data readings for the o2 sensors and check the voltage is switching.quick question - did you have the o2 sensors renewed?
