A dirty throttle body may cause low engine idle speed or frequent stalling, as oily residue blocks air flow in the throttle when the throttle is closed. Throttle body cleaning may be necessary to correct this condition. Our technicians caution against spraying cleaner directly onto the throttle body as this may damage the throttle position sensor (TPS).

Just Recently when i come to a stop the car stalls most of the time. The idle is decreasing to the point that the car wants to cut-off and most of the time it does. Without my doing the idle races-up in order to keep the car running but before it stalls the green cruise light flashes but no check engine light.
Car has a rough idle at that tends to stick around 1600 rpms. Occassionally the car won't start and tends to die while driving. Engine codes are showing 53, 24, and 66. What are these codes?
The car felt like it wanted to stall, making a loud noise. The malfunction light came on and the oil light. The car stalled and would not start. It was towed to a Chrysler dealer and they told me, I needed a throttle body service, a fan module harness and an oil pressure switch. What a let down and high expense.
stalls once warm and idle speed keeps dropping lower and lower
