How do you adjust elec choke on a 86 f 150 4.8 4bbl?

To adjust the electric choke on a 1986 Ford F-150 with a 4.8L engine and a 4-barrel carburetor, first ensure the engine is cold. Disconnect the choke's electrical connector and loosen the screw on the choke housing. Rotate the choke housing until the choke plate is in the fully closed position, then back it off slightly to allow for a small gap. Reconnect the electrical connector and start the engine to check the choke operation; it should open gradually as the engine warms up.
