Hello im working on a 2010 gmc acadia with the 3.6L 
It has timing codes for Intake and Exaust on bank 1 and Exaust on bank 2
It runs decent but does not idle good, fuel trims are all over the place
I took a waveforum of the Intake and Exaust on bank 1 and of the crank sensor I'm having trouble understanding what im looking at (new to using a scope)
I looked up a picture of a known good cam crank on here and the crank signal of the known good looks diffrent than mine 
hoping someone can help me understand, thank you

The timing codes are pretty cut and dry on this engine platform, if it's identified a timing problem, then it's pretty much going to need a new timing set.
It's hard to see the entire captures on phone, but it is almost as if your entire capture is inverted compared to Pico capture if I am seeing this correct.
