1. Check reliability of all connections with weight. Check conducting and system sockets. Weakening of electric connections and bad contact to weight can cause many malfunctions which are often perceived as failures of the engine.
2. Check degree of a zaryazhennost of the battery. Normal operation of sensors and actuation mechanisms of a dosage of fuel depends on supply voltage.
3. Check a condition of the air filter, – pollution of a filtering element can cause essential deterioration of operational indicators, including profitability.
4. If the fused safety lock is found, replace it and check work of the corresponding chain. If the safety lock fuses again, find and eliminate malfunction.
5. Check tightness of the channel of an air line from the filter to an inlet collector. Existence подсоса air in an air line leads to excessive pauperization of a mix. Check also a condition of the vacuum hoses connected to an inlet collector.
6. Remove from the butterfly valve chamber an air line and check existence of deposits of a deposit and resinous deposits. At pollution wash out the case an aerosol cleaner of the carburetor and clean a toothbrush (at first be convinced that the cleaner is harmless to oxygen and converter sensors).
7. On the working engine put a stethoscope to each of nozzles and hear to the characteristic clicks indicating normal work of nozzles. If the stethoscope is absent, use a long screw-driver. The termination of a screw-driver put to a nozzle, and an ear approach to the handle.
8. If listening yields doubtful results, check nozzles by means of the light indicator, having included it in the nozzle socket. Start the engine and be convinced that on each socket of a nozzle light flashes.
9. On the idle engine disconnect sockets from nozzles and check resistance of each nozzle. Resistance of each nozzle should be within 13,4–14,2 Ohm. If resistance differs, a nozzle replace.
10. Other checks should be carried out in car-care center as malfunction of the control unit can be the reason of abnormal work of system.
