AnswerHi Johnette -
Try checking your exhaust system. Could be excessive back pressure from a collapsed catalytic converter, exhaust pipe, etc.
One way to check it is to remove the exhaust pipe at the manifold and run the car. It will be loud, but at least you will know after this test.
Please get back to me on what you find.
Hope this helps -
