Re: Engine cut out at idle
I'm guessing it is fine when cold. If so, I'd suspect a dirty throttle body. This may be for various reasons, a blocked oil seperator in the cam cover, and considerable oil consumption.
Remove the induction pipe from the throttle body. If is is dirty, clean it. Some spirit may work, but accessory shops sell dedicated throttle body clearner in aerosols. Wipe the throttle venturi and butterfly valve with a cotton cloth after spraying. Open the valve and clean behind the butterfly valve. Be careful not to cut yourself, as sometimes the back of the valve is sharp and will slice through fingertip skin very easily. Once all clean, take the car out for a drive of at least 10 miles. During this drive, allow the engine to reach full working temperature, and make a point of using full throttle and 7200rpm on a number of occasions. This will perform a 'drive cycle' and allow the ECM to relearn all the operating perameters of the engine.
Your idle should now be fine. If not, let us know.
BTW, welcome to AO, and I hope you enjoy your Alfa. I hope that, although the spirit is a bit diluted, you find it an enjoyable car to drive and economic to run. Beware oil consumption and remember 36K cam belt and tensioner changes.
