PO 302 code, running really rough. what is common on this? I haven't tried anything but pull code at Oreilly.
Welcome to! My name is DriveFast71(Ron) and I will do my best to answer all of your questions completely and accurately.

There are a few things that can cause a single-cylinder misfire. Inspect the distributor cap, plug wire, and spark plug for cylinder #2. If these all check ok, you will next need to inspect the fuel injector, intake air leaks around cylinder #2 and ultimately, cylinder compression. Cylinder #2 is the one closest to the front of the vehicle, passenger's side.
