2003 Yukon SLT scanner live status problems

[zmann96]

Took it for a ride this morning ( 113 miles) up north hills, highway and city streets. I varied my speed on the highway a bit. I got back no codes. I'll check the trims when it gets light out ( it's not inspected so did want any cop issues). I want to thank everyone that help me out with things to check and eliminate.

Wish I had read this 3 years ago LOL. I never thought this was the problem because I heard no tic or sound of the leaks. Thanks for sharing this
