    Hello, could do with some help on this one, not used to vauxhalls, this is an early one single point injection, am using sykes to read data, its all i have....
    The problem is lack of power in a big way, the car will sit and idle ok but drive it down the road and it feels like you are being held back.
    There are no fault codes, but looking at the live data on idle I get 600mb manifold pressure, air temp reads -31 (cannot find a sensor) and oxygen sensor seems to switch very fast, are these right?
    A new cat has been fitted and the rear exhaust does not appear blocked. There does not appear to be any air leaks. A new egr valve has been fitted recenty, not by us, so I dont know if that was trying to cure this fault or not.

    Any help or advice would be great,

    Rod Dench
