screws. Tighten screws to 5 N

Im (40 in. lbs.) torque.

(3) Connect negative cable to battery.

(4) With the ignition key in ON position, access

the DRBII scan tool ASD Fuel System Test to pres-
surize the fuel system. Check for leaks.

(5) Reinstall air cleaner assembly.

FUEL INJECTOR

The fuel injector is installed in the top of the throt-

tle body. The injector is covered by a cap.

REMOVAL

(1) Remove air cleaner assembly.
(2) Perform Fuel System Pressure Release proce-

dure.

(3) Disconnect negative cable from battery.
(4) Remove injector cap holddown screw (Torx-

head).

(5) With two small screwdrivers, lift the top off the

injector using the slots provided (Fig. 7).

(6) Using a small screwdriver placed in the hole in

the front of the electrical connector, gently pry the
injector from the pod (Fig. 8).
