Overhaul (Swift SOHC)

Remove fuel injector from throttle body. See INJECTOR (TBI) under FUEL SYSTEM. DO NOT soak injector in any type of solvent or cleaner.
Remove throttle position sensor, throttle switch (M/T) and coolant (water) temperature sensor from throttle body. See Fig 3 . Remove attaching screws and separate upper and lower bodies.
DO NOT soak any electrical device or air valve in solvent or other cleaner. DO NOT put drills or wires into passages. Clean upper and lower passages with compressed air only.
Assemble upper and lower bodies with new gasket. Torque upper-to-lower body attaching screws to 25-35 INCH lbs. (2.8-3.9 N.m).
Install coolant (water) temperature sensor. Torque sensor to 15-22 ft. lbs (20-30 N.m). Install fuel injector. See INJECTOR (TBI). Apply thread locking compound to injector cover mounting screws and install cover.
Torque injector cover screws to 25-35 INCH lbs. (2.8-3.9 N.m).
On auto. trans. models, install throttle position sensor so adjusting holes slightly cover mounting bolt holes. See Fig 1 . Turn sensor so mounting holes align.
