And again a histrum from the department “We find gradually all possible Easter eggs”. I was surprised or annoyed for a while that in the petrol operation the idle speed is too high with warm(!) engine (1,200 to 1,300 rpm) that the gasoline consumption increases with short-range operation *extreme* and for that the idle speed is much too low in the gas operation (engine usually goes out). Moreover, the gas consumption is too high, and in the gas operation the expected power is not reached. However, the gas problems I had not connected with the petrol problems, because the controls of both systems are separated. Today I had the opportunity to come to a workshop, which is with the gas system model installed with me (Zavoli RE.GA.L, Venturi) know. The guys have checked the system from the front to the back and then opened to me immediately that after their opinion the Lambdasonde is defective. That is because the gas system is with. Thus the emptyness in the gas operation would not be too bad.
