Ok, well just recently i ran into some trouble where my timing belt has slipped and i had to have it replaced. Well soon after that my alternator went out and I replaced that. After my timing belt had slipped my car has had trouble accelerating, it would coast with the pedal to the floor. I would have to switch from droppin it into neutral revvin the engine to 1.5RPMS slammin it in drive and doing it again until the rpm got to 2000, When it does the car accelerates perfect. I know my transmission is going out. But I would like to know if its not that and start small before I go big. If any of you guy's could help me it would be greatly appreciated. It also has a major oil leak and smoke rises from the hood. I just recently replaced the oil and the filter its on there tight, The oil leaks from the back of the engine onto the exhaust. Any idea's on that one too? Thank's!
