sounds like something to do with ECU. its probably ova fueling which is why it misses.
my 1st 1.3sr nova's carb neva used to cut off properly so when it heated up it would still be on and the car would'nt run. and it'd run shit as soon as it was started from cold aswell

the only thing that could rule over fueling out, would be the fact that the ecu light does'nt come on and i would have thought that the O2 sensor would pick it up seeing as theres loadsa smoke.
does the temp guage work? mite be that the ecu can't detect that the engines hot so is still chucking in loadsa fuel

measures wot sort of gases are going through the exhaust. ur best bet is to get it to vauxhall and get it on the diagnostic machine. if not do the paper clip test and see wot u get

A lambda sensor measures the amount of unburnt oxygen in the exhaust. The ecu uses that to decide whether to sling more or less fuel into the chamber. If it reads like there's lots of unburnt oxygen then the ecu will throw in more fuel and you'll get smoke. But like Danny said, that would probably give you an engine light when you start ragging it.
What could be wrong is, if there's a hole somewhere then the lambda sensor can actually be getting more oxygen from outside the car, which will make overfuelling happen.
