Question about 2000 Alfa Romeo 156
Hi, recently noticed that my Alpha Romeo 156 (petrol) was producing too much (white) smoke from the exhaust but did not think too much about it. Whilst driving the 'motor control system failure' switched on and I quickly pulled over and stopped the car. I switched the car back on and the 'sytems check' declared the car OK. So I proceeded to make my way back home, but when changing gears I realised that the car lost a bit of strength in acceleration between gears (almost as if it wanted to choke out) and at this point the warning light came on again. I stopped the car once more, but this time the lights remained on after I started it once more. What worries me is that I serviced the car only a week before this happened. Any help would be great.
It does not sound like a head gasket and it is not likely to be the ECU. It is more likely electrical:
1st Check the battery - Variations in voltage really upset the Alfas
2nd Electrical - most likely candidates are ignition coils; stressed wiring; or Lambda sensors. Finding a reputable mechanic that can correctly identify the issue is the biggest challenge otherwise it can cost $ in trouble shooting.

Motor control system failure means either 2 things
1 A fault with the ecu
2 A fault with the exhaust and lambda sensors

Could be the cambelt slipping, when was it changed last?
