I have a 1971 Dodge challenger 318 auto with electronic ignition. It started stalling after the engine comes to operating temperature and when I come to a stop, not in neutral or park. It does not stall when the engine is cold, only when it is hot, in gear at a stop. I have checked around the carb abd replaced the vacume lines. I rebuilt the carb and exchanged the distributer with another I have. I also exchanged the electronic ignition controll box and the regulator and still have the same problem. Does anyone have any experience with this or can offer any help?Thanks
change the ignition coil...unless its a fuel issue..do you have a timing light to hook over the coil wire and toss light with tape on trigger under a wiper blade and take a test drive...test fuel pump..cold engine.. disconnect ignition so no sparks..disconnect fuel line at carb... extend into a clean clear plastic 2 or 3 liter bottle.. have helper crank engine for 15 seconds while you watch pulses of fuel from end of hose..do you get nice full pulses..??? not diminishing.. then hook up a pressure gauge to the end of the hose.. or hold finger over end and have friend crank for 5 seconds.. hold finger for 15 seconds then release.. is there fuel pressure..is this a 2 hose fuel pump or a 3... there have been issues with the return line back to the tank loosing its restrictor so the fuel pressure is low enough that it cannot push it thru the inlet when the engine is above 2000 RPMs.. these are a few things to check ... you can check for coil output.. when it stalls...position.. DO NOT HOLD distributer cap end of coil wire 1/2" away from metal and have somebody crank engine while you observe.. nice bright blue snappy spark... not dim orange whimppy..
