It could be a coil. It could be a plug. It could be a problem with a fuel injector. Is your check engine light on? Has your check engine light come on and then gone off? You should scan your engine and see if there is a cylinder that has low contribution. Misfire. How bad is the vibration?

yes, the information you received could be what your vibration is. But you should write down what the actual codes were so they can be used to help diagnose problems that you have.
