Yep, this is typical of an engine misfire which sounds like what is happening, do you have a check engine light on? If so, we should run the codes which will tell us which cylinder is having a problem. Can I ask if the engine has been tuned up recently? If not, this can be the problem.

Here are two guides to help us see what's going on and how to fix the problem:

Please upload videos of the problem so we can see what's going on.
