Had an intermittent misfire that wasn't even enough to trigger a P030X code.

In this video, I go over:

Mode $6 to see which cylinder is misfiring when you don't have a code.
Looking at fuel trims to see if it is an indication of fuel or ignition related
Looking at scan data to see if a bad injector is detected
Using an injector pulser/tester to see if we can hear the injector firing (also can be used with Fuel pressure gauge to check flow rate
