This is a long shot, but that feeling of wanting to stall may be caused by a clogged PCV valve. Thats what caused it on my car at least. They aren't expensive. My stealership put mine in for under $14.
BTW, @75k you might wanna consider new spark plugs and wires if you've still got the original ones in there. It might not solve all your probs but it would help with performance.
Oh....heres another long shot: Somebody please correct me if I'm wrong, but that jerking might perhaps be due to a bad fuel pump?
