Corsa b running prob

[yulaw5110]

Hey lads the missus has a 98 corsa b . its a 5 door,cylinder ecotech petrol. the car is bit slow to strat it always starts but turns over a bit more than a normal car , i figured that the crank position sensor was dodgy so i replaced it today and its still bit crap to start. but this is not the main problem , when driving on the motorway if u put the foot to the floor the car pulls for a sec r 2 but then starts to stumble and loose power , the engine management light comes on, when u back off the throttle the car recovers and the light goes off after 20 r so seconds, U can get the car up to motorway speeds but u have to be slow and steady bout it . any ideas, mass air flow meter??

have you cleaned all the crankcase vent hoses or checked them for leaks.

also well worth doing the paper clip test
