Hi, I have a problem with my Vtec it is a B16A2 98'. I live in Quito- Ecuador, and as u know I live in one of the highest cities in the world(More than 2890 m above sea level). Well when I am at the sea level i dont have problems with my vtec, but when i come back home..... i have problems with it.. it cut off and come back in second and third shift.... it turns on at 5600 rpm but at 7000rpm it turns off. I have cheked the solenoide with a ligth and it works fine. I dont know waht to do.. Please if someone knows let me know any advice
