A few years ago I had a similar problem with my 1976 Dodge Truck. It turned out that I had to replace the Power Brake Unit. It had an internal Vacuum leak. Christopher had some great tips so if you haven't checked for Vacuum leaks try troubleshooting for any. Cracks in hoses? Does the "F" have the Vacuum tank up inside the drivers side fender like the "G" does ? If so check the hoses to and from the tank and check the Vacuun tank for rust and deterioration. If it's real rusty it could have pinholes which would cause poor vacuum. Good Luck and I hope this is of some help.

Ryan might be right about possible convertor reasons but would imagine that a real uncommon reason, so maybe not the first thing to go for? ( And Ryan maybe chill out on 'tongue in cheek re earlier recently criticising' aussies/me who ask whether widows' children who contact the Club to find out what a few old 300s are worth after their dad dies - and in hindsight I was also a bit hard on the person/woman who contacted the Club for not knowing, yet lately who knows exactly what a unrestored 300F or 300G convert is worth, and she normally did the right thing in asking the 'experts', us, even if she/family had already sort of knew from what their dad had told them -one/I/you never should assume they knew/cared so little for their dad they did not know?!) (And a second point, just because one's husband/father/brother dies, does that automatically mean 'everyone whoever' is left behind is fair game for whomever is first there with a chequebook/cash - Ryamn/others/300 lovers, I hope not?!) First check any vacuum hoses, carb gasket leaks, brake booster diaphragm, etc, then go for the less usual/difficult ones Ryan suggests.

If you rule out timing, vacuum leaks, ignition, and valvetrain problems you shouldn't overlook the converter. Especially if it's a newer rebuilt unit. If they malfunction, (lock up too early basically) they're like a clutch that isn't completely disengaging. Just a thought....Ryan Hill To: chrysler300@xxxxxxxxxxxxxxxxxxx: paul_martin78ca@xxxxxxxxxxxx: Fri, 22 Aug 2008 10:07:10 -0700Subject: [Chrysler300] 300F stallingI am having issues with my 300F stalling when approaching a stop. I have all the linkages and anti stall pot set according to factory specs. In order to avoid the stalling i change to neutral as I approach a stop, and the select D when I need to accellerate. The car is very sluggish on accelleration as though it is running way too lean. Any suggestions?Paul300F Vancouver BC__________________________________________________________Yahoo!
