Hello Guys,

I wonder if you could help me - we have a 2.0 57 plate vivaro - which has been starting fine but the problem comes when you are trying to accerlarate away from say a standing start at a junction for example - if you push the accerlator slowly and gradually its not too bad, but when you go to oush the accerlator normally it is so sluggish. We have changed the MAF sensor - a friend has one of the diagnositc readers and it is coming up P0303 which I believe means a misfire on cylinder 3? Does this sound like an injector issue or could it be something else? My local mechanic will not remove the injectors as apparetnly they are common to snap so I do have an appointment with the main dealer on friday morning for a proper diagnostic test - but I just wondered if there wa anything else I could try before taking it to the main dealer, I am being told approx 500-600 to replace one injector - if it is that.

Any help would be really appreciated.
