2003 Chrysler 300M Problems

Stalling or Low Engine Idle Speed Due to Dirty Throttle Body

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).

Damaged Cam Position Sensor May Cause Engine Problems

A damaged cam position sensor (or its wires and connector) can cause intermittent stalling, stumbles, or hard starting.

Poor Heat Output Due to Air in Cooling System After Service

Poor output from the heater and/or engine overheating can be caused by air left in the cooling system after the cooling system has been serviced. Our technicians tell us the proper coolant fill procedure should be used to prevent this problem from occurring.
