My car has 194000 miles.
My car has an automatic transmission.

The data being sent to the vehicles computer can be observed on a professional scan tool and may shed some light on the problems. The engine coolant temp sensor may cause issues if the sensor is sending false information telling the computer the engine is much colder or hotter than it actually is and can affect fueling and cooling. You may also have a large vacuum leak. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look at the vehicle, hook to a scanner to observe the data and offer a more personal diagnosis.
