My car is playing up. When its been left overnight it drives normal,but as soon as the temp gets close to 90 the management light comes on and it starts back firing.Took it to a garage and they said could be spark plugs,so i bought new 1s, or could be the sensor at the side off the air filter. Can any1 help...

DO you go into limp home mode?

Backfire? a puff of smoke that what you mean?

If you stop turn engine off for a minute or so, does the problem clear?

I would be driving along and my Vectra (SRI CDTI 150 Auto 2008) will start running funny and the fuel consumption becomes irratic. If I pull over and turn the engine off then on again it rectifies itself but this could happen 10 times on a journey! Really frustrating, anyone know what the problem might be?
