: Check Engine Light-Evap Code....Help

01-17-08, 10:48 PM
Any ideas how I can find an EVAP leak without a smoke machine? I have been able to erradicate all of my gremlins in my '98 Catera except this check engine light coming on after a couple days of driving. My gas cap appears to be in good condition....Any ideas?
