I just bought myself a 2005 Maserati quattroport the warranty has expired on the car and I took it in to some guy that specializes in italian cars (might have been a big mistake not going to maserati/Ferrari)anyways I got a full tune-up on the car, just after 10min of driving the car from the shop, the cars rpm jump to 5000 and blue smoke is coming out of the back ( not little bit a smoke enough to cover the block, kinda like wen some one does a massive burnout) i pull over and the engine turns off by itself, i try starting it again and it starts but only runs for about 5 to 10 sec and the car shut off kinda like if some of the pistons are not running. I any 1 know WTF am i suppose to do plz post. The car only has 47350km on it and i also see some oil leak from the bottom. (also the battery light came on if that is any more help)
