Yep. We jumped the diagnostic connector before setting. They’re definitely the original knock sensors.
You got a solid plan by looking for a smoke machine to see if there any leaks. I found tons of leaks and may still have one since I've been getting P0171 quite a bit lately. How is your long term fuel trim number?
Side note:
Since you're thinking of "renewing" your OEM charcoal canister, I'll give you my input. I did this and ran with it for years but always had some vapor smell on hot days or after a hard run in 4low. After the turbo went in and I sourced a smoke machine, my OEM renewed canister had leaks around the perimeter where JB weld was applied. Ordered me one from Autozone and called it done. I haven't smelled fuel vapor while wheeling in 100+ deg in UT few weeks back.
For what it's worth, I'm not sure if it's worth the effort to renew the OEM canister. Just my .02.
