They say replacing an air filter will save me gas (which I might do since my car has over 170k miles), but to me it seems like a dirty air filter would just limit and amount of air that goes into the engine just like a throttle does. Would it really make a difference?

It's probably been replaced by a previous owner (I bought it 6000 miles ago) but I wouldn't be surprised if it hasn't because there are so many other problems with it that should have also been taken care of (valve cover gasket, axle boot, coolant leak, dashboard lights, huge dents, completely worn out tires, etc...), though I've taken care of the more serious problems. Considering it's a cheap beaten up old car, I won't pour any more money than necessary into it so I'll just get a cheap one.
