My car has 135000 miles.
My car has an automatic transmission.

Under your hood you should have a VECI label which gives you a vacuum diagram. If not, you could buy a service manual from a company like Haynes or order an All-Data DIY (do it yourself) subscription for fairly cheap.

Finding replacement parts will be difficult to say the least on a ’92. You will probably have to find salvage parts depending on what they are. An experienced technician might be able to make it run better. However, those sound like emissions part which should not be modified.

If you need assistance, a certified mobile mechanic from YourMechanic can inspect your vehicle’s issues at your home or office.
