When I start the engine , sometimes it is running perfect. But sometimes the engine seems to be ok until I put my foot on the accelerator and there is no power, particularly when I am pulling away at a junction. So now I test my car always by stopping on a by-road and pulling away, if missing , no power, I stop the car and switch off ignition. I then start the car and pull away , normally this works first time and car is normal power, sometimes I have to stop and start twice. Once car is running it is ok for ever until I stop and start car. And I have to go through same procedure. This happens whether car is hot or cold. Went to a small garage and he tested all and thinks it may be a Lambda sensor, front one. But he is not sure. Went to vauxhall he said it willl cost money, a lot to try and find the fault. Milliage is 53000.

You need to post up the fault codes for us to help you more,
see the maint guides to reading the fault codes on the 2.2 :y

Can you get codes read?
Worth trying pedal test here: http://www.omegaowners.com/forum/index.php?topic=90581.0 (http://www.omegaowners.com/forum/index.php?topic=90581.0)
Not many 2.2's work though for that, so might need a cheap code reader.
Start off with basics, have you checked the plugs for oil/water?
Any dash lights on?

I do not have fault codes, but once car would not start and RAC told me there are a few fault codes showing. 1 . Lambda sensor 2. Cam sensor.
My engine management light is always on but car once running is great.

That will give you definite problems. Worth also giving the throttle body a good clean plus the breather system

Cam sensor will often cause other random codes, replace with a genuine part, nice easy DIY job :y
