The easiest thing to do is test drive another car of the same spec/year and compare its performance.

Its quite a heavy car for a 1.2 NA engine, with a 14 second 0-62mph (thrashed mercilessly) time its not going to be a lazy easy drive.

Be thankful you don't have the slug like 1.0 litre of pure motoring hell.

Thanks a lot guys for your comments, but does anyone know how to remedy the problem.

I feel that it is the way the engine is programmed, ie. vauxhall has developed a good little car in the Corsa, but hasn't came up with an answer to increase MPG, so they may have programmed the engine to accelerate gently in order to conserve fuel. This slightly increased MPG. might look better when promoting the car. I might be entirely wrong, but what is the soluion to it, since my last Corsa with the same engine, and been round the clock, could kick the veritable **** out of this new one.

Thanks craig for your input. This non mechanical design of pedal to throttel linkage definately adds to the problem, especially when accelerating and 5th.gear is selected, the car falls back as if the engine had died, then very slowly accelerates. All this time you are looking at the MPG. read-out which is down arround 17-23 MPG.

No airflow meter fitted on this model.
