You probably can't adjust anything that would improve it since the combustion is computer controlled. That of course means that there is another problem causing it like a clogged EGR value, or a bad oxygen sensor, or a bunch of other things. You didn't mention if your car has fule injection or carburetor which is another avenue to explore.
I would suggest going to Autozone and having them plug their OBD1 tester in and see if they get any codes out of the computer. I bet they do, then you will at least know what you are dealing with.
Changing oxygen sensors can be quite difficult if the are rusted in. The also get a healthy price for them. I think they are around 90 bucks each, but I'm not exactly sure.
Good luck with the project.
