What do ya mean cuts out? won't idle or just stops running altogether?

the car will idle fine all the time but when you press the throtle it just wants to cut out ! It doesnt quite stop but sounds like its not getting enough fuel and if i press the throtle really fast it will splutter and back fire. and once someone stopped and said i had sparks fly out the exhuast and the cat was glowing bright red !!! :-\

Over fuelling? check airflow meter and oxygen sensor. Get the exhaust checked for co content.

i have the same problem as you i have an 8v gti it mis fires on accelerating and theer jut seems to be lack of power, im ahving the throttl body air and pump washed , basically carb cleaned, as this is what someone has suggested and its not hard to do and costs jus the money for cleaning products and a bit of time. also having the idle  sensor body done. try it and tell me how you get on i have heard this suggestion many times in the forums.

i have now relaced the air flow meter and still no luck !!
Ihave replaced the relays as sugested and noticed tha if i pull relay no:30 position 3 out the engine still keeps running !! so is that the ECU relay or the fuel pump relay ? and is that normal ?
