when i first start the car the choke light comes on, and when i floor it i can fell that my 4 barrel carburetor isnt opening. then when the engine warms up the light eventually goes away and iam able to open all 4 barrels. whats the problem??????

 

Check the voltage at the wire on the choke thermostat (with it disconnected, ignition on). It should be 12V. If not, you've got a problem with the supply, either the relay or a fuse.
