Don't forget that the snapshot was taken on an engine with no load. 3,000 RPM is achieved with a very small throttle opening & only a little fuel is required (hence the short injection duration). I have a similar snapshot from an identical car with no running issues & it looks very similar. I can post it if anyone has the patience to look. I also did a road test snapshot on the sick Tigra with an acceleration test & cruising down hill & uphill captures.

Thanks for the coment. I do try to be thorough, but this one has beat me
I have scoped most of scopable things on this & nothing stands out as odd. I did a road test data snapshot with a long full throttle acceleration & the O2 sensor displayed rich throughout, so fuel isn't lacking in this instance. I also did a "visual" on the spray pattern of all injectors & they are nice.
I am resigned to the conclusion that it is just a tired donkey. I even rang Vauxhall Tecgnical for the first time ever & he agreed. Although I was disappointed that the guy didn't mention the crank pulley issues that these are plagued with. (I deliberatley left that out of my "test performed" list, to see if it would be mentioned. )
