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).Google+

Chrysler Concorde Stalling or Low Engine Idle Speed Due to Dirty Throttle Body
Chrysler Concorde Problem
Engines Affected: 2.7L V6, 3.2L V6, 3.5L V6
Average Mileage: 148,250 mi (100,000 mi - 216,000 mi)
Engine idle drops at idle in gear to 400-450 rpm, causing oil pressure light to flicker, there is no knocking associated with it, and touch the gas pedal and it's fine.

low idle and stalling do to speed control module. took off vacuum hose and made sure check valve was left on the vacuum to motor and all is well. dropping into low gear is safety built into trans from too low of idle. ;)
