Hi Pete

Yeah I do agree with that and I didn't try that when the vehicle was in. I've just tried adapting a test for gdi injectors and found number 4 can't hold back its fuel when not firing? Will let you know the outcome Saturday. Otherwise I'm getting stumped as to why its running so rich. I have scoped air mass meter and to me it checks out fine as everything else really does pass the tests. Doesn't help every part is genuine suzuki and costs the earth compared to the German world. Oh and customer let me know last night this is a problem that he believes has been ongoing for almost a year. Lovely

Regards
