How do you fix a vacuum leak on a 95 Jeep Cherokee?
I have found the best way is to find the main vacuum line. You can take it off the power break booster. Then light yourself a big fat cigar and using your mouth blow smoke into the line. The smoke will identify where the leak is because you can see the smoke coming out. For about 200.00 you can buy the real tool. For less then 1.00 you can get a cigar.
