Title: Stalling when warm in gear
Post by: GeotechDuck on June 08, 2023, 02:04:41 PM
Hi Everyone,
I could use a little advice.  When I drive at freeway speed for hours the car runs perfectly.  However, if I get into stop and go traffic in town, the car dies when I come to a complete stop while in gear (auto) after about 15-20 minutes of driving.  I can restart in park and it idles perfectly.  If I try to shift to drive without giving it some gas, it dies again.  It runs perfectly once I get it going again, as long as I don't stop in gear.   

Temp gauge reads a little warm.  It usually sits at the "M" in TEMP, but always has for as long as I can remember.  Years ago I tested actual temperature with thermometer and heat gun and it was well within range.     

Fuel pump and fuel filer have recently been replaced.
I removed the ignition coil and don't hear any indication of fluid when i shake it.
Fuel lines are away from block and headers.

Should I just go ahead and replace the coil?  Other ideas?

Check dashpot adjustment on carburetor?

Could be high float level. Get the engine to normal temp, then shut it off and look down the butterflies. If the butterflies are wet and or the boosters are dripping, you have a high flow level. Ethanol gas makes the problem worse.
