или 39 причини и решения на проблеми за атмосферен и турбо мотор.
или два листа хартия в жабката против уроки. Откакто съм ги сложил при кабела- нищо не се обажда.
Систематизирал съм ги по азбучен ред (горе-долу) за по-лесно търсене, мислих да ги извадя по симптоми, но е хубаво да се четат подред за обща култура.
