P0442 - Smoke Test
Have P0442 (small EVAP leak) code. Used to have P0455. That went away when I took off canister control valve and cleaned. Guess P0442 always there and was covered up by P0455. Planning on doing smoke test with a cigar and hand suction pump. Anyone tried this. Since CCV is normally open, figured I'll connnect up there.

Where the fitting goes into the cannister there are o-rings. Went to hardware store and found some of same size. Fixed leak and code.
