vectra sri misfire.

As an ex-miggy owner i need your help again guys.i now have a vectra 2.2 sri 150(still keeping it vaux).it has developed a fault and im not sure what it is.when on the motorway the traction control light flashes and the car starts to stutter.like a misfire type of thing.it gets worse as the speed increases but starts around 70 mph.any help would be fantastic guys.cheers

Going on what you have said, it seems the misfire is caused by an ABS signal suggesting that wheel spin is occuring and downing the power. (Or is that just an omega TC feature?)

if that is right how do i cure it.

You need a decent code reader that can check ABS/Traction control systems to see what fault is causing the issue,could be as simple as a dodgey sensor
