I'm not sure if this is a 5.7 specific topic or not, but here goes. Can anyone tell me what conditions have to be met so our PCMs do our evap system tests? I believe the fuel tank has to be between 1/4 and 3/4, it has to be driven on the highway for 55 mph for a few minutes, it has to sit overnight, it has to be below 90 degrees... what else? I've been meeting these conditions for a few days but my evap tests won't run. I want to get my emissions done, but this test has to show complete first. Any ideas? Thanks!
