i have a corsa 1litre 3 cylinder the engine emissions are high i've had the idle control valve renewed the mass air flow sensor renewed the gas recirculation valve renewed the lambda sensor renewed but still high emissions it runs well and starts well but it stalls when i drop the revs. but will tick over no problem if i slowly lower the revs and the idle control valve takes over any ideas how to cure my car problems ? any suggestions what so ever ?
Hi Snowball,
Considering what you have renewed I think the only thing left is the catolytic converter in the exhaust system has a fault, could be pricey unless you can get a spurious part. Hope that helps. FT
