Models with carburetor
1. Disconnect the negative cable from the battery.
2. Remove the air filter (see Section 7).
3. Press the gas pedal and unscrew the lock nut to the groove on the cable housing.
Fig. 8.3 To remove the throttle control cable, press the rod (A), release the adjusting lock nut (B) and twist it until it goes beyond the groove on the casing (C), move the groove to the slot in the bracket and remove the cable
4. Release the cable (see fig. 8.3).
5. Disconnect the cable from the throttle linkage.
6. Disconnect the other end of the cable from the control pedal (work under the instrument panel).
7. Remove the cable from the support brackets on the camshaft cover and the clamps connecting the throttle and transmission valve control cables (automatic transmission).
8. Turn the plugs in the engine compartment wall 90° and pull the cable out from the engine side (when installing the cable, lubricate the plug to avoid leaks).
9. Installation is carried out in the reverse order of removal.
10. Adjusting the cable.
- a) Make sure that the cable moves smoothly without jamming;
- 6) Start the engine and check the deflection of the cable at the throttle linkage.

It should be within 4-9 mm. Otherwise, loosen the lock nut, turn the adjusting nut to provide the desired deflection and tighten the lock nut.
- c) after adjustment, make sure (here you will need an assistant) in free and full throttle travel when pressing the gas pedal and returning it to the idle position when releasing the pedal.
Fuel Injected Models
11. Disconnect the negative cable from the battery.
12. Remove the air duct between the throttle body and the air filter (see Section 6).
13. Remove the throttle control cable (see fig. 8.3).
14. Rotate the throttle shaft to release the cable and disconnect it from the shaft.
15. Disconnect the cable from the throttle pedal.
16. To remove the cable, turn the plug in the engine compartment wall 90°. Pull the cable out from the engine side.
17. Installation is carried out in the reverse order of removal.
18. Cable adjustment:
- a) Shake the cable to remove excess solid lubricant.
- b) Use the adjusting nut to set the distance between the groove on the cable and the bracket to 9 mm.
- c) Tighten the lock nut and check the deflection near the throttle rod. The deflection should be within 9-13 mm. Otherwise, adjust it.
- d) After adjustment, use an assistant to check that the throttle valve is fully open and returns to the idle position.
- d) If the vehicle is equipped with an automatic transmission, adjust the transmission valve drive cable (see Chapter 7B).
- f) If the vehicle is equipped with a speed control device ("cruise control"), contact the service station to adjust it.
