When worn the rubber seals, especially the nozzle of the air filter, the motor can be sucked air. As a result, the cylinder receives a lean fuel mixture. As a result, the car loses momentum, the engine is working, the “Check” does not light up. If you encounter such problem before sending to service center for diagnostics try to check for air leaks on your own. It’s not necessary to have the smoke generator. If the leak is that after restoring the tightness of the machine have to earn the right.
What you’ll need:
- plastic bag;
- compressor with adapter;
- the thin hose.
The process of finding the leak
To quickly determine whether there is a serious leak, you should disconnect the sensor mass air flow together with a pipe and cut it by hand with the engine running.
Before that is to succumb to the gas. As a result, the nozzle vacuum will be created and the motor stops. We need to continue to keep the palm.
If the leak is, it will be possible to hear the hiss with which the air comes in through small cracks in the seals. If there is no sound, and the air pipe curled from the vacuum is not straightened, the choke is missing and the reason for the poor performance of the motor in something else.
For a more detailed inspection of the tightness you can disconnect the tube from the sensor mass air flow and lay in between them a plastic bag. Then the pipe is clamped by the clamp back.
Next on the compressor hose is installed with an adapter kit, and it fitted with a thin tube such as is used on the frill.
Then you need to pump air into the intake manifold through any fitting having removed with his hose. Air is pumped into the receiver as long as the pipe from the filter will not swell in a region of the corrugation to the elasticity of the ball. After turning off the compressor need to hear there is no hiss.
When you create a vacuum in the manifold, or Vice versa pumping him pressure you want to view on the subject of the leak in the first place the tube from the filter, as it often cracks.
Also air can enter through the probe, the IAC valve, the pipe from the charcoal canister, throttle gasket, o-rings, injectors and the intake manifold, loose hose clamps on the air tube.
Replacing worn gaskets and tightening the clamps, you can repair the leak, thereby restoring the normal operation of the engine.
