It is not uncommon for the power steering rack to develop a fluid leak requiring replacement of the rack assembly. Loss of power steering fluid may also cause an abnormal noise and damage to the power steering pump
at around 130,000 miles transmission began to slip when slowing and then accelerating rapidly. At 182,000 mi. Trans. Started making a growling sound, I had it replaced with a GM. Factory remanufactured unit for $ 3,200 still going strong at 225,00 mi..
May have been repairable if I had taken it in when the slipping started.
The leveling system air compressor head has a relief valve in it that corrodes and sticks over time. Each time the car is started, the compressor should cycle to pressurize the system and then the release pressure as needed to establish level. The condition becomes apparent when the rear of the car raises a little at a time until the air shocks are destroyed, requiring replacement of the rear shocks and the air compressor head.

The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.
An intake manifold vacuum leak can develop from a variety of sources, often causing illumination of the Check Engine Light with codes P0171 & P0174 stored. Thorough diagnoses will be necessary to pinpoint the cause in order to make the correct repairs. A "smoke" machine is often used to isolate the cause of difficult to find vacuum leaks.
