Do a COMPLETE tune up on it. I mean everything, you're probably getting horrendous gas mileage with it too I'm betting.

1) Drain all the oil, pull off oil pan and replace the gasket. Install a new filter and fill up with oil.
2) Drain all the transmission fluid and pull the tranny pan. I'd suggest getting a new filter and gasket on that as well, then fill it back up with tranny fluid, check your owners manual for exact fluid capacity as I have seemed to forgotten.
3) Change out the spark plugs.
4) Change out the fuel filter. Depending on the car, it may either be inside the engine bay, or underneath the car on the passenger side.
5) If you want to spend the extra money, I'd say invest in some new spark plug wires.

A simple tune up can go a long ways with our cars, and you have to keep it maintined regularly (like any other car) if you want it to last long and be a good car.
