I mentioned on here I was getting another vectra Sri cdti 150, it's a 55reg and it's a really good price but it has a misfire under 2k, is it easy enough to see if the part has come off the manifold, I'm hoping it's just the egr valve, anyway I'm going to Doncaster to see it in the morning but iv just seen an astra Sri 2.0t 5 miles from the vectra so thought I'd go and take a look, how many mpg will I get out of the astra around town? Any help would be much appreciated
