For the past 6 months my car will shudder when you first turn it on and then after 5 odd mins will sound as though running normally, but when driving it will lose power if you try to accelorate over 40 or go up hill even slight inclines also when going round corners and sporadically when at lights or from sitting in traffic it passed it's mot with flying colours and has been in the garage 10 times I had a service and the diagnostics showed mass air flow and lamba sensors both were changed no difference the egr was changed
no difference does anyone know anything no garages or vauxhall themselves have an answer please help before I go insane!!

I know nothing of motor cars but in the old motors I have owned when this happens...

it will lose power if you try to accelorate over 40 or go up hill even slight inclines

It has been the clutch wearing out - and or - not enough fuel reaching the engine for the power demand being placed on it.

very difficult to determine your problem when a garage cant fathom out your fault,only thing I can tell you are the problems i have encountered with corsas,maf meters,egr`s and crank sensors have caused problems with motors I know of and also blocked cat caused problems you are describing,up at local scrappy they say they get through loads of coil packs also,and one last thing which I havent encountered which a lot of people have mentioned are the dashboard clocks causing problems
