RE: My '71 4.5 runs like poo!
I was going to suggest draining the tank and using fresh gas or running a bottle of 'heat' in the tank to clear out any moisture, but then I see you can get it running well until it warms up.
Is it possible heat from the engine is causing the incoming gas to become vapor before it hits the engine? Forgive me, but is this condition called "heat soak"? I've known of a few cases of this happening in a few carb'ed Ford Capris.
Another thought is in the emission control system (if you have it.) Could it be failing to make an adjustment after the car gets to a certain running temperature.
Again, my appologies since I'm new to these cars but I'm just throwing out ideas.
