I will be driving, and the engine will hiccup. Sometimes is will be fine afterwards, and just keep driving. Other times it will feel like it running on two or three cylinders, the check engine light will be on but still won't populate a code. I can turn off the ignition and it will start back up and be fine. Sometimes when I pull over it will stall. Attached is a video of what the engine sounds like when it acts like all cylinders are not firing. The problem is not an ignition coil as they have been replaced.
Any ideas?
