When it stops or slows down to a almost stop it dies

My car has 345003 miles.
My car has an automatic transmission.

Hi there. There could be an issue with the throttle body sticking and not adjusting correctly. Check the idle speed when the vehicle is parked in park and then in gear. The engine idle should be around 1000 rpm’s in park and about 850 rpm’s in drive or gear. If the rpm’s are in the general area, then check the fuel supply and see if the fuel pump on the engine is pumping enough fuel to the engine fuel management system. If there is no enough fuel flow, then the engine will stall out at the vehicle is slowing down. Also, check for a misfire on the engine. Check the spark plugs and wires for a good solid spark. If there is no spark, then either the spark plug is fouled out or the wire could be burned. Then replace the spark plugs and wires as a set. If the engine is running good and does not stall out until the vehicle is in motion, then the torque converter clutch may be staying active and causing the engine to stall out. Try putting the transmission in neutral then slow down the vehicle. If the engine runs normal and does not try to stall out, then the problem lies within the torque converter or transmission. If the engine still try’s to stall out, then there is a problem with the fuel or ignition system. If you need help with your engine stalling then I recommend seeking out a professional, such as one from Your Mechanic, to help you.
