hi, i took my car into a garage to get the cambelt changed, and they have royally messed it up!!! i went to pick it up and they said it was good to drive away, i pulled out and drove away slowly for a couple of minuites, then i put my foot down a bit and the car loses a lot of power its like the turbo is not working, i went back to the garage and it started kickin out black smoke from the exhaust, cutting out, and a loud whistling noise, can anybody shed any light on this as they havnt repaired it yet
