How do i Chase a vavcum leak on a 1986 Ford F 150
I use starter fluid on the area that I think got a vac leak, but you need to be careful, its flammable, and while spraying you will notice a change in the idle in the place where is a leak.
Not many DIY'ers have access to leak detector machines. You can build one with a paint can, a cheap cigar, and several feet of tubing. Check the net.
