Truck acting very weird

[SouthernComanche]

So about a  week ago my trucks pcv line popped out and got burnt on the manifold. Sigh, but I jerryrigged it together and its held up exceptionally well, until now (I think) So I turned out onto the road and the truck stays in first, cuts my throttle and starts backfiring like crazy, like I had 2 step or something. I quickly pulled off, and turned off the truck. After turning it back on it had no problems, until I got to a stop light, where it just died. I turned it back on and tried to limp it back to school (I was on lunch) and it wanted to die every single stop, it got to the point where I put it in neutral and looked like a dummy revving my truck at a light to keep it on. Well after I made it back, I turned it off, and quickly inspected it. My PCV is still good, everything looks A-OK. I turned it on and it didnt try to die even in gear. I had to go to class which is were I'm at now and I'm at a loss for ideas.

Do some sensor testing and see which ones are acting up or not functioning.
