anyone for help
darren in mk ...
|My Dad's got an 'X' plate astra ( no taste ! ). He had same problem, took it to local garage ( who service my MGF ). They sent ECU to a specialist, who diagnosed some kind of electronic fault ( black arts as far as I'm concerned ). Said specialist repaired unit for about 1/3 of cost of new one!|
|My parents have a '99 Astra and the ECU went on that. Apparently a known problem area, so after a few letters of complaint Vauxhall went halves on the replacement cost.|
Had this problem ages ago (brand new s reg at the time) intermittent and sometimes causes stalling. Its the crank sensor in our case and about 200 quid to fix
|My old Passat 16v used to do this and if you pulled away really hard it would stall - caused by cracks in inlet trunking after the airflow meter. The meter/body was body mounted and the torque reaction caused the the engine to move back a bit, stretches trunking, mixture goes to pot and kangeroo-a-Passat!! Took ages to find that one!|
|I don't know much about Vauxhall engine management systems. What kind of ignition system do they use? If this had been a pre-2001 MGF, I would point the finger at the distributor cap and rotor arm - but I would expect a late '03 car to use a wasted spark system...? |
Crank sensor would seem a sensible place to start - along with the airflow meter (or do they use a throttle position sensor?)
