hi guys... thought i should try u geniuses... my car was running fine... all the sudden i lost power... before that the turbo was making this whistle noise and was accelerating fine... but all the sudden it doesnt have power , theres smoke coming out of the pipe like a mada.... the turbo seems to be working , but before anything.. i have checked the fuel filters under the hood , their both clean.. someone said it might be the filter in the tank.. ... im thinking of either a filter,, a turbo ,, or a fuel injection pump..... what do u think.. ?? thought and comments highly appreciated.. ..
