Has the water pump, timing belt, and belt idler bearings been replaced? If not you are due to have that done.
Also power steering pump belt, ault/AC belt.
Plugs and plug wires should have been replace about 60,000 if not you need to replace them and the '97 has a distributor cap and rotor. Other sensors when the computer tells you through the check enging light.
If it is an automatic it is time for the third fluid and filter change.
I always replace my spark plugs/wires and fuel filters every 30k miles. This prevents a lot of things. I don't need to check them for ohms or signs of old age-it's like waiting for it to deteriorate, not a smart move. I would encourage everyone to replace them every 30k.
