It's overly touchy sometimes and then sometimes there's a dead section at the bottom, then VROOM it "catches" and revs way more than you want. Bucks and stuff too if it's running shitty. Makes it very hard to drive the car smoothly. Also, bogs on decel when you push the clutch in and sometimes dies coming to a stop. Seems to do this when I'm coming to a stop quickly and don't catch it beforehand. It'll dip down to 4-500 rpm and then "catch" itself most of the time, but then once it dies, my headlights fuck up for the next few minutes until they've cooled down or something and you restart....

Super weird.
Oh and it could also be your battery is dying since you said your headlights fuck up which I assume they're fluttering? If you jump a car with a completely dead battery (not rechargeable) it will idle poorly and the lights will flutter, etc. The engine is basically trying to generate electricity to keep itself running
