If you can get the codes. That would be great. As it stands. Hesitation, stumbling, poor engine performance, problem acceleration can be caused by a MAP Sensor, Throttle Position Sensor, Mass Air Flow sensor, coolant sensor. A collapsed catalytic converter can also cause a problem accelerating.
With 150K on it, it could be the fuel pump too.
We need to figure out if it is electrical or fuel related. Pull a plug wire off of the spark plug and insert something into the end of it and have someone try to start the car and have the metal object really close to a piece of metal on the engine and see if you are getting a good strong popping blue spark. Don't have your hands on any part of the metal! If there is no spark, then it is electrical.
If you are getting good spark then spray some starting fluid in the throttle body and try to start it and see if it tries to start then.
You may need to get a fuel pressure check on the fuel pump to ensure it is putting out okay. We will see.
My suggestion try to pull codes and do the checks above for spark and fuel. Let me know.
