1997 Chrysler Sebring "service engine soon" warning

My car is a SEBRING convertible JXi - 2.5L V6 (153CI) VIN (H)with 86,000 miles. I have driven it for 20 years and, since I am 85 years old, hope to keep it until I stop driving. I made an appointment at the Chrysler dealer for to-morrow (probably a mistake) to see if they can interpret the codes better. The only repair suggested by my mechanic is the replacement of the engine/transmission mounds that are cracked and separated, an expensive but not immediately needed.
