I have a 2007 Yukon that only starts ticking when I am parked at idle for 5 to 10 min,,,starts then gets loud. Once I rev the engine or start driving it disappears....Had the whole top of motor redone 3 yrs ago by a dealer.....Broke now and wondering if maybe have someone shut off the afm could possibly stop it being it only happens when I am idling

  I put my black bear on to see if it pulled up any codes. No DTC found. When the shop checked there was no check engine lights either. I drove the truck around today and nothing popped up light or code wise. However, whatever plug in module the shop used could find codes just like the dealership could. I should of took pictures of the shops tablet to show what they see.

- Is 2027 GMC Yukon Getting a 682-HP Supercharged V8?
  
  By CaptPat51 · Posted 1 hour ago
  
  Would you supercharge the 6.2L on a 2021 GMC Yukon Denali XL with ProCharger?.... 605HP is the stated number without going crazy - it's not the LT4 682HP package, but I'm tempted to install it... This vehicle was ... not... recalled on the engine swap - but I don't really know if that means ...don't do it... or do it;) Maybe i should start a prediction market pool on it in case it blows up;) Any thoughts appreciated - I already OWN the supercharger - stopped the installation when the recall was announced and now it's taking up space in storage until I can solve an electrical issue with the vehicle... 4th GMC suburban-equivalent truck - I like them a lot - when they don't a) discharge their batteries randomly, or b) throw a rod at highway speeds;)

  We tested the sleep mode with an ammeter in series with the negative battery terminal - 30amp fused - so we do know the actual shutdown and non-shutdown current draws and timing of the shutdown sequence. We just have no protocol information to determine what module is issuing the (likely) network management (NM) keep alive.
