Visual check

The leakage in the field of system of an admission opens access to "unrecorded" air, that is air which is not considered at a monitor and consequently essentially disturbs mix preparation. The mix nekontrolirovanno is impoverished. More distinctly than all this malfunction is shown in unstable frequency of rotation when idling.

PERFORMANCE ORDER

To check density of a prileganiye of vacuum hoses and existence of cracks. All hoses on an inlet collector (for example the amplifier of brakes, preliminary heating of inlet air, the electromagnetic valve of system of evaporation of fuel) should be checked.
To warm up the engine and to leave it to work at single turns, to open a cowl cover.
To sprinkle from a spray containing fuel spray (for example, «Startpilot») the case of throttle knot, consolidation of flanges of inlet channels and pipelines to units operated by depression (to disconnect plug connection from a lambda probe).
If when spraying a certain place frequency of rotation of the engine changes, means, there was a leakage.
it is possible to distinguish a leakage топливопровода?
were repeatedly disconnected and are again connected? Corrosion or inept actions can lead to insufficient contact.
Attentively consider tips of separate components of system of injection. Contacts not to bend, and to process spray.
