I was driving this car and all of a sudden, it surges kind of like it
putters where it dies and then it goes and then dies (I am getting
whiplash doing this). Eventually it dies at a stop usually then it
takes a couple of starts after holding down the gas pedal then go into
gear.(My head snaps back usually). Today, it finally decided it did not
want to start up at all. Its not getting gas at all it seems and I hear
like a loud thud come from the exhaust as it blows through. Any ideas
what can be causing this?
