Re: [Chrysler300] 300 G Fast Idle

Sounds like you have a problem with the choke pull-off system.  I don't have specs for your fast idle speed, but without regard to the actual setting it should come back to a slightly fast idle immediately after the engine starts (of course also after you press the gas pedal a little to unload the fast idle cam).  If your pull-off is a vacuum diaphragm you should suspect that it has ruptured.  If it is a piston in the choke's hot air/bi-metal spring chamber you should suspect the vacuum passage to be clogged.

You should not have to wait for operating temperature before you can have a reasonable idle speed.  When working properly there is a step-wise decline in idle speed as the engine warms up, but you should never have to deal with such a high idle speed for an extended time------good way to break a band in the transmission.

 What is the correct fast idle RPM ? Mine starts out at around 2,000 and doesn't come off until the temperature gauge reaches normal. Not sure how to adjust. Appreciate any help.
