Take an injector and remove from it a sealing ring. Sealing rings of removed injectors at assemblage are subject to replacement without fail!
7. Before installation plant on an injector a new sealing ring. Slightly grease a ring with pure impellent oil and plant an injector in a corresponding nest in a fuel highway.
8. Make sure of correctness of landing of all injectors, then establish into place a fixing plate (). Strongly tighten screws of fastening of a plate, then connect to an injector (ам) electroconducting.
9. Return into place directing electroconductings and strongly draw its bolts to the pipeline.
10. Establish the air sleeve connecting an air cleaner with the case of a throttle, then connect a negative wire to the battery, start the engine and check up injectors on presence of signs of leaks.

1. Release a fixing clamp and disunite a contact socket of electroconducting of a potentiometer.

2. Turn out two fixing screws and remove a potentiometer from the throttle case.
3. Installation is made upside-down. Track for correctness of introduction of a potentiometer in gearing with an axis throttle заслонки.

1. Release a fixing clamp and disunite a contact socket of electroconducting of the motor.

2. Turn out two fixing screws and remove the motor from the throttle case.
3. Installation is made upside-down.

1. Remove a potentiometer of an axis throttle заслонки (the subsection "the Potentiometer of an axis throttle заслонки" see above).
2. Release a fixing clamp and disunite a contact socket of electroconducting of the gauge.
3. Turn out the screw of fastening of a socket of the gauge to the top part of the case of a throttle, then accurately take the gauge from the throttle case. Check up a condition of a sealing ring, in case of need make replacement.
4. Installation is made upside-down. Do not forget to replace the failed sealing ring. Track correctness of introduction of a potentiometer in gearing with an axis throttle заслонки.

1. Release a fixing clamp and disunite a contact socket of electroconducting of a heating element.

2. Turn out the screw () fastenings of a contact socket of a heating element to the throttle case, then separate a socket and cautiously take an element from the throttle case. Check up a condition of a sealing ring, in case of need make replacement.
3. Installation is made upside-down. Do not forget to replace the failed sealing ring. Track, that electroconducting of a heating element has not appeared is clamped at a screw tightening (ов) socket fastenings.

1. Disconnect a negative wire from the battery.
2. Remove the air sleeve connecting an air cleaner with the case of a throttle (Removal and installation of assemblage of an air cleaner see).
3. Disconnect a vacuum tube from a regulator of pressure of fuel.
4. Release a fixing clamp and disconnect various hoses from the top part of a fuel highway.
5. Without forgetting about the preventions made in section of Sbrasyvanie of pressure in the power supply system, ослабьте fixing collars also disconnect hoses of giving and return of fuel from a fuel highway. At assemblage it is necessary to replace factory collars of braided type more practical screw or worm.
6. Release lock clamps and disunite contact sockets of electroconducting of four injectors of injection.
7. Give three fixing bolts and accurately remove assemblage of a fuel highway with injectors from the inlet pipeline. Take the removed assemblage from the car. Remove sealing rings from end faces of all injectors (at assemblage they are subject to replacement without fail).
8. Remove a lock ring () and take a corresponding injector () from a fuel highway. Remove the top sealing ring () from each of the removed injectors. All sealing rings at assemblage are subject to replacement!
9. Installation is made upside-down. Pay attention to following moments:
   a) do not forget to establish on all acting in film injectors new sealing rings;
   b) For simplification of landing of injectors it is necessary to grease their sealing rings with pure impellent oil slightly;
   c) In summary the engine should be started and checked up on presence of signs of leaks of fuel.

1. Remove the throttle case (Removal and installation of the case of a throttle see).
2. Disconnect electroconducting, then give two fixing screws and remove a potentiometer from the throttle case.
3. At installation track correctness of introduction of a potentiometer in gearing with an axis заслонки. Strongly tighten fixing screws.
4. Establish into place the throttle case (Removal and installation of the case of a throttle see).

1. Remove from a box a cover, then disunite a socket of electroconducting ECU.

2. Take ECU from the box. In case of need give fixing nuts and separate the block from an assembly plate.

3. Installation is made upside-down. Track reliability of fixing of an electric socket.

1. At first disconnect a negative wire from the battery.
2. Give three fixing nuts and liberate the gauge from below from a basic arm.
3. Release a clamp and disconnect from the gauge electroconducting and a vacuum hose. Remove the gauge from the car.
4. Installation is made upside-down.

1. Remove the throttle case (Removal and installation of the case of a throttle see), then turn out two fixing screws and remove from the case of a throttle a potentiometer of an axis throttle заслонки.
2. Walk on electroconducting back from the gauge to a contact socket of electroconducting. Turn out the screw of fastening of a socket to the throttle case.
3. Accurately remove the gauge from the regular place and take it from the throttle case. Check up a condition of a sealing ring, in case of need make replacement.
4. Installation is made upside-down. Do not forget to replace the failed sealing ring. Track correctness of introduction of a potentiometer in gearing with an axis throttle заслонки.

1. For the purpose of providing of access to the gauge prop up противооткатными boots back wheels, then поддомкратьте redock of the car and establish it on props. Access to the gauge from under the car now will open.
2. Walk on electroconducting back from the gauge to a contact socket of electroconducting. Disconnect electroconducting of the gauge from the basic plait.
3. Turn out a bolt of fastening of the gauge to the block of cylinders and take the gauge from under the car.
4. Installation is made upside-down. Track correctness of a lining of electroconducting and reliability of a tightening of a fixing bolt.
