99 pontiac bonneville
i was driving on the highway today and all of a sudden my cars oil gage
went up and then down then the car died. any reason why this would
happen? the mechanic said that the engine is locked up but i can still start
the car and drive it about 3 blocks before it dies. it has been running just
perfect before and just all of a sudden dies now. i have been hard on it
barely, but all the other times i have been treating it nice. it need a oil
change as well but the mechanic said that would not help it! help me please!
any reason why it would do this to me?
