We need to do a couple things to start. First, run through this guide on the basics of misfires.

Then we need to check codes to see which cylinders are misfiring.

Then we need to check for vacuum leaks and make sure that is not causing any issues.

Once we check for these things we should have a pretty good idea what to do next. Thanks
