it seems like whenever i drive my car or whenever its hot outside my car dies out? the idle speed is normal whenever i start up the car, but whenever drivin for bout 5 miles the idle speed is very low to the point when i let go of the accelerater the car shakes and sometimes shuts off. another way it shuts off is when im accelerating and i push on the accelerator but the car doesnt accelerate and then i let go of the pedal and then it shuts off?? Throttle Sensor, Fuel Pump, Fuel Filter, Tune-up having got 1since i bought it 6 months ago? it seems like the engine is like over heating or something but idk 170,000 miles on it
