RE: [Chrysler300] Throttle Valve Adjustment?

["christopher beilby" <thelastbestgenius@xxxxxxxxxxx>]

Stalling can be many reasons, but often when a motor dies when put in 
gear/drive, it often can be too lean a mixture - that can be caused by too 
lean an idle mixture screw adjustment, or some sort of vacuum leak 
somewhere, or wear in carby where the throttle butterfly shafts are.

Also if the brake booster is sucking air because rubber diaphragm is/has 
perished/failing, then when one puts car in gear and also at same time foot 
put on brake, that can see the booster cause vacuum loss - leaning out and 
stalling motor.

Good luck, Christopher in oz
