ive had a problem with my astra coupe turbo.
the car will idle fine then all of a sudden cut out.
if i hold the car at 2000rpm in any gear it coughs and splutters
then if i dip off the throttle coming into a corner or junction the car dips off
ive replaced the air flow meter and the car runs even worse.
so ive tried uncliping the plug from the airflow sensor and tucking it in the cable trunking behind the engine. and the car runs perfectly boosts ok
but the engine management light is still on.
any ideas what the problem could be???
as i am completely stumped
the car does have the astra 2.2airbox with a K&N panel filter on it
