I have taken it to several workshops, the Somda Landa has changed, the catalyst was stuck by consumption, we changed it TB following the car with the same symptoms.> Later we cabied the injectors, they checked in the BMW the caudalimetro and put the switchboard in parameters.> The caudalimetro is perfect. The compression of the engine tb is all the cylinders in 10.5 They are fine.

can you help me please ???

Hello, this problem in your car is caused by some factors such as the engine's tempera is important to advance it if it controls it or is the question of the spark plugs that are indicated for your car and the air filter unve

Hello, thank you very much for the response, the engine the temperature and progress of time would come out in the machine diagnosis the fault?
I mean that the spark plugs better all original?

Have you put the car to a gas analyzer? Does it have a good time or does it give them high? If so, you have a very high gas mixture and there the high consuno. At the cold in cold it goes well or made black fumes? With the diagnosis they checked the temperature sensor?

Right now I don't know how your car injection system will be but surely carry a system to facilitate cold starting, if this system does not work well and is activated permanently, be it a bypass or a cold starting injector or both the consumption would be high and the reduced power, it would be recommended that you review these systems.
