Enjoy the forum.
Quick story to all. I joined the NV200 forum because my van was playing up power wise. I was advised on a thread I read, to change the fuel filter first - hey presto it worked - it must have been an air leak as I had to put the original back on as I bought the wrong one and it all works with no spluttering! It’d been like that for a year so today is a good day. Forums are good, Amen
