Once really, really, really warm the Cougar is actually running better than ever. But unless it warms up for an excessively long period of time (maybe 20 minutes), it will quit when idling and in gear. In park or neutral it is fine. This is a new issue - previously I only needed like 5 minutes.
The car is a '69 with a 390, Holley Carb w/electric choke, c6 trans. The engine is to the best of my knowledge stock. Vacuum checks good (steady at about 16") and idle timing is roughly 15°BTC
So I guess my questions would be:
1. How long should the choke stay closed?
2. How long should the fast idle cam stay "on?"
3. Someone suggested that my thermostat could be stuck open causing the engine to "cool" when not necessary. Seems logical to me - thoughts?
4. Anything I missed? Should I be able to tell anything by the temperature gauge?
And just for perfect clarity - after the car has been running for a while - it runs fine. I guess I have no proof that it is temperature related....
