peugeot 406

slm friends please help me. i became a new member in the forum I have a 2000 model peugeot 406 st 2.0 vehicle.It has gasoline / lpg at 190 thousand km. have the same problem. Could it be from injectors? The malfunction lamp is not lit at all. There is no problem when I am in the gas that confuses my head. Did I switch to gasoline, the vehicle stops and idle wheezing while idling. what else can happen I'm waiting for your help

I had the same problem, I changed my brain, and 106 ...

don't do my brains

Gas is self-gasing in my car. The tachometer rises and falls. but nothing has changed, still the same. I do not understand what this problem is doing.

While I was running idle in my vehicle, I played the cycle time up and down, sometimes I can not recover, I want to recover.

I had that problem, I still have gas on my own, I said injector, I changed (I gave 2 billion).

I found a great resource for you, but in English. This problem can arise from different places, as long as I have understood and as I understand. What can be done and the possible causes of malfunction are lined up and there are also videos. If anyone has problems in English, I can spare some time.

Well, the site looks like a beautiful brother, but we don't understand.

The engine fluctuation is usually caused by a fault in the management of the fuel system or in the driveline. Fuel management system monitors emission output and engine performance with the help of sensors and transfers them to the brain. In this way, fuel mixture, timing and emission and fuel management system are taken under control. While the engine is running, the brain of the vehicle searches to find the correct fuel mixture rate and timing. In some cases, the brain of the vehicle cannot correctly capture one or more of these settings and cause fluctuation. These situations are listed below.

· Diagonastic Error Codes: With the error codes read, the sensor or system that cannot fulfill the task can be detected.

• Measuring Fuel Pressure : It is the measurement of the pressure of the fuel coming with the fuel pressure instrument. Connect the pressure gauge to the test section on the fuel pipe. The pressure value changes according to the vehicle. If the fuel pressure is not sufficient, the fuel pump needs to be replaced.

· Clogged Fuel Filter: The clogged fuel filter can also cause this ripple. The system should be tried by replacing the fuel filter with a new one.

· Motor Control for Vacuum Leakage: If there is a vacuum leak in the motor, it will cause the sensors to read incorrectly and transmit to the brain, thereby fluctuating the motor. The system is programmed to run at a predetermined value. If there is a leak in the vacuum, the value read from the sensor will be wrong, causing the motor to fluctuate powerlessly and jerkily. Check the air intake assembly for any tears, openness. In case of mistake, replace the parts with a new one. Sometimes a vacuum leak can be heard when the hood opens.

· Exhaustion in Exhaust System: The exhaust system in the vehicles is designed to produce maximum 3 pounds of exhaust smoke at full throttle. This means that in order for the engine to start comfortably at a given moment, it should not push more than 3 pounds of exhaust fumes. If the catalytic converter is obstructed or detached, it will dislodge the entire exhaust system, resulting in engine ripple.

· Poor or Faulty Spark Plug Control:

· Slip in Clutch

In another place I saw a presentation in response to your question. I said let me share.
Check for leaks at the air inlets on the engine assembly, and make sure that the vehicle's coolant is not low. Drain some coolant a little while the engine is hot. In this way, if there is no air left in the system.

friends, let me let you know, but there is no problem when my vehicle is working at LPG. Something might happen in the gasoline fuel channels written by our Koliva friend.
