Vauxhall Zafira keeps juddering

I went thru all the same things mate, even changed ,cleaned and removed the egr valve, as with most zafiras if nothing will fix the running issues I would point you to getting the engine ecu tested, this will cause all the running problems mentioned and more and will throw all sorts of ECU codes, like coil pack, multiple misfire, egr fault, throttle fault, and especially o2 sensor faults, I've been there done it the hard way with the zafira

Nice one mate will get it checked

Hopeithwlps, zafiras are great cars,we did thousands of miles in ours but when they are running t
Like this you just want to burn them,

Pls let us know the outcome

Alright mate its had a new ecu on it

New main ECU, or the engine ECU? Did you replace it, just asking as thats the only way I would believe if it had a new ECU, its the engine ECU that IMHO is the issue

the one with all the wires pluged in to it at the right hand side

hi thanks for everything it looks like it was the ingecters as changend them and it seems to be running fine now thanks again
