iirc not a dirty maf kinda car, try changing plugs/wires/cap/rotor to start.
Bitter's right about that car not having the MAF.
And he's also right that the plugs/wires/cap/rotor are an excellent start and a very cheap replacement if you do it yourself (unless it's obvious those are already new, then don't worry about changing them). A bad distributor cap can cause all kinds of havoc, although in some cases the car can idle like a dream and it's only when you're accelerating that you have problems.
It may also be that the wires for two of the cylinders are swapped, or maybe the wires just aren't seated well. Firing order is 1342 on that engine-- make sure the wires are routed properly. Timing itself could be off, too. Someone with some experience can reset to the idle timing without a timing light (it may be a little bit closer to top-dead center done that way, but if the idle improves with a hand adjustment that'll let you limp along a little better).
You might be surprised at how much life is left in an old car like this. Unless you see plumes of smoke or steam coming out the back, it'll probably be serviceable for some miles to come.
It's hard to find a good local mechanic, but if you can find one, latch on to him (or her). Explain your situation, and try to work out a payment plan with them rather than going with a payday loan company.
It's situations like yours that I wish public transportation were more available in most of the US, though...
