Feel the shaking all over, in the seats and driving.

Is the engine misfiring? Has the check engine light come on?

Recently had a smog check down and the oxygen senor was changed. New
spark plubs and wires replaced. The cadilac converter was replaced. The engine light didn't come on. The engine misfiring I don't know for sure.
