Remove air intake cover from throttle valve injection housing - note seal ring.   Disconnect wiring harness plug (1) from idle speed stepper motor.   Detach idle speed stepper motor from throttle body.     Important!    To prevent the housing and the idle speed stepper motor from being damaged during installation, the distance between piston and flange must not be greater than 28 mm. With a deviation, carefully press in the piston.

  Install, Connect

Connect wiring harness plug to idle speed stepper motor.  

Notice: 

Before assembling components of the intake system (hoses, connections, etc.), they must be cleaned of any possible contamination (grease, oil, etc.). When tightening the hose clamps, be sure to observe exactly the tightening torque of 3.5 Nm / 2.6 lbf. ft.  

  Important!   

It is only ensured that the intake system is free of leaks, thus ensuring operational safety of the engine, if the hose clamps are tightened correctly to the prescribed tightening torque.
