2003 Vauxhall Astra Front Wheel Drive Manual 70000 miles

When I switch on ignition car does not rev past 2000 revs. After leaving engine on for 5 - 10 mins it revs up to 2500, but basically when I drive it, I cant accelerate, it does not give gas, does not rev. I can only just about drive in 1st gear cant get past that.

Have the car plugged into a diagnostic computer to check for fault codes stored on the cars PCM (computer). It could be in limp mode or a throttle position sensor fault

Ok thanks will do that.

I asked few garages most saying air flow mass sensor or electrical fault, because also the exhaust back box is broken and requires a new one or either weilding.
One mechanic told me its most probably cam sensor as these are common faults in astra's and I think he is correct, it may well be that.

He told me to disconnect the air flow pipe and then start and rev car which I did, but noticed underneath air flow pipe there was a switch disconnected which I think leads to camshaft. I connected that back and started car. At first it would not start but eventually did and started revving fine but then just cut out.

So I disconnected that again and then same thing, car starts but does not rev past 2000
