Topic: Instalatie gpl cangas, golf 4 1.6 16v azd

Salut, am un golf 4 cu instalatie gpl cangas si am probleme, mi se aprinse check-ul in bord si nu porneste la prima cheie dimineata, uneori se si opreste cat este rece, pana se incalzeste putin. As vrea sa cumpar cablu pentru aceasta instalatie, sa mi-o reglez singur, deoarece am fost la montator, a dat 2-3 click-uri la relanti si atat, nici nu am plecat bine de acolo si s-a aprins check-ul. Am curatat senzorul Map, clapeta de acceleratie, egr, schimbat kit membrane vaporizator, filtre.
