(acha fuel station matters most in Pakistan). acha mechanic milna 2nd biggest issue, jo classic bethy woh engine noise sunty, 90% jin k pas computer devices hain unko pata hi nhi default values ka and how to achieve that, unko just reset all ka option hi pata, sensors values kia aa rahi hain and kia ani chahiay. agar apki average set nhi to IDSI models mai biggest issue wiring ka hota hay, although meri purani hi chal rahi but a close friend achieve 18+ just by replace wiring coz old wiring pc ko thek value hi nhi dy rahi hoti to problem hoty hain
