Thank you Dave! The high idling finishes after a while when the engine is hot, but it takes too much time to get stabilized, so as you said, I also think it could be the o2 sensor/EGR or the idle control valve. Thanks again for your hospitality! Now I will check every post in your forum related to this.
Yo guys! My name is Álvaro and I'm from Jaén, a little province located in the south of Spain. I use as third car a Honda Civic MB3 1.5 115hp with motor code D15Z8 from year 2000. I hope I will learn many things from all of you, because I'm suffering a high idling and an elevated fuel consumption, but leaving aside this, the car is really nice. Regards!
