20. Remove the (4) fasteners retaining the stabilizer bar and

21. Remove the engine breather hose from the valve cover.
22. Loosen the hose clamp between the throttle body and intake
adaptor.
23. Disconnect the T-MAP, IAC and TPS sensor connectors
from throttle body.
24. Remove the remaining bolt attaching the airbox to the
frame (see photo).
25. Remove the airbox and throttle body from the vehicle as an
assembly. Take care in not allowing the throttle cable to
bend excessively or kink. Carefully place the assembly on
the floor next to the vehicle. Insert a shop towel into the
engine intake adaptor to prevent dirt from entering the
engine.
NOTE: Ensure throttle cable is not being
excessively bent or kinked while removed from the
vehicle.
26. Mark the fuel injector harnesses to identify MAG and PTO
harness connections to aid during reassembly. Disconnect
the fuel injector harnesses.
NOTE: The fuel injector harness connector and
locking spring is bonded to the fuel injectors with an
epoxy mix. DO NOT attempt to disconnect the
connector from the fuel injectors. Damage will occur
to the injector and/or harness if attempting to
separate at that location. Separate the fuel injector
from the vehicle by disconnecting at the end of the
harness as shown.
IMPORTANT: Take note of PTO and MAG fuel injector
harness connectors before disconnecting them. The
harnesses are different and can not
be connected
incorrectly (PTO - Gray; MAG - Black).
