Hello, I need some help, I’ve had an increased verb with my Astra GSI 16v for a long time with short distance/city traffic. In the past this was always 8.5 liters. Now I’m at 11liters. Today I’ve only driven long distance 300km with ca120-130Km/h, there’s the consumption in order: 6.5liters. I’ve been driving the car for 10 years now: Astra GSI 16V Bauj.1993 C20XE Motonik 2.8 KM:Stand 233000KM were renewed: Air mass meter, Lamda probe, Thermostat, Termofühler both, cranks I have the impression that the engine is running too fat. Where is the idle control valve for the engine? The design is different than with the Ecotech engine. Can you clean it? Unfortunately, I did not find anything suitable with the search function. I will also put the same post into the Calibra forum again, so that many people can help me, hope this is ok for you…. Gru ß Sid
