I was driving my pathfinder when all of a sudden it started to misfire in 5th gear upon acceleration. Dropped it into 4th and still misfire on acceleration. Same in 3rd, 2nd, and 1st until I came to a stop where I had to give it gas just to keep it at idle. Took off, still misfiring and got to 2nd when the car just died and coasted to the side of the road. Next day, changed out the fuel filter, started it up and began to idle fine after a few seconds of stumbling. Took it for a test drive when 3 minutes in the drive, started to stumble on acceleration in 3rd, downshifted to 2nd with same result until It died again, but this time all the electronics were out. Warning lights, interior and exterior lights. Checked the battery and found only 1.9 volts. Took battery out to charge and all of sudden had 12 volts when I checked it outside of the car. WTF??? Put battery back in after cleaning terminals on battery and on harness to check alternator. Car did start and idle fine, about a minute, just enough to check that alternator was charging battery when car started to stumble and misfire again to the point where it sounded it was about to die until I shut it off. Changed out the distributor cap, rotor, and plugs with the same results. I've included a video to show what it sounds like to get a better idea what I'm talking about (yes I know, I have an exhaust leak lol). What else can I check or what direction should I go in next? I'm maybe thinking timing or something more with ignition, am I right? Any suggestions is greatly appreciated as this is my daily driver and I need running ASAP. Thanks.
