There are some very simple maintenance items you can do on your car to help keep her healthy. Changing the oil and coolant is high on the list and it sounds like you have that covered. The air filter is also important and should be changed every 12,000 - 15,000 miles, depending upon driving conditions. If you have an oiled cotton gauze type filter, be aware that these allow more dirt into an engine than a paper filter.
Behind your air cleaner is a Mass Air Flow sensor (MAF) that has tiny heated wires in it. You can buy CRC MAF Cleaner at any parts store. Unclip the air lid, remove two clamps and a wiring plug to remove the sensor. Liberally spray down the inside with the cleaner. Do not attempt to wipe down the inside as you can damage the tiny wires.
While you have the MAF off, you can also look into your throttle body to see how dirty it is. Again, there is a spray cleaner that can be utilized to remove the gunk. This can be wiped out so long as you are careful of the Idle Air Control valve (IAC) on the side of the throttle body. If you notice a large buildup of oil inside the throttle body and intake, it could be coming from your Positive Crankcase Ventilation valve (PCV). Let us know what you find. Note that with age, the PCV hoses tend to deteriorate and a vacuum leak will cause issues.
The fuel filters on our cars should be changed every 25,000 - 30,000 miles. It is located under the car, on the driver side, in front of the rear axle. It does take a set of line wrenches and a special tool to release the filter. Neither are very expensive and any motorhead friends probably have these in their toolboxes. Other things include flushing the brake fluid and power steering fluid, changing belts, cleaning debris from the radiator, and cleaning and re-lubing the brake caliper pins.
If you need help with anything, please do not hesitate to ask. Our cars are now all going on at least 9 years old, and it is better to be proactive than reactive.
