If its not your vehicle, how do you know for sure its a vacumn leak and not something worse? Not everybody tells the truth when trying to sell their vehicle! Ask them to take it to their local auto repair shop and get it fixed first. Say you will buy it after its fixed. Average vacumn leaks are under $100.00. Goodluck
spend the 100.00 to have it ck'd out by your mech, it will be the best investment you will ever make
