What engine is in your car?

Lots of black smoke would suggest lots of unburnt fuel. The most likely cause would be intercooler O rings (very easy & cheap fix and VERY common) or a split on your intercooler pipe(s). If its the MAF (Mass Air Flow Sensor) that's faulty you can just try unplugging it. If it is this then unplugging will make an instant difference.
ok will give it a go mamy thanks steve
Let us know how you get on:-)

Sounds like you still have an air leak somewhere.
