96 850 GLT EVAP small leak Cigar method

Post by joe_pinehill »

Has anyone tried the cigar method of finding a leak? I thinking of putting a hose on one of the nipples on the vacuum line tree and blowing cigar smoke into it to hunt for the P0402 small leak code.

I've used a couple of cigarettes in a garden pump sprayer and it was good enough to find where I thought it was leaking anyway. The crack was on the top of the hose so it was hard to find without smoke.
