My 2001 Chrysler 300 M frequently stalls on decel when approaching intersection. It idles fluctuates up and down then the oil light flashes and then stays on, sometimes the car stalls out at a light?
Also, there is knocking with idle and at low speeds?
Engine stall or RPM fluctuates
at idle.
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
