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.
