I did the CRC this weekend for the first time and am kicking myself for not doing it before.

My truck does have the Air Raid Jr so getting to the throttle body was as simple as loosening up on hose clamp.

 

Given how simple this is how often are people doing it?

I was thinking every 2nd oil change?

Can we assume you're talking about the CRC GDI intake valve cleaner?

This is what CRC say.

Use this intake cleaner every 10,000 miles, or at every oil change, to prevent deposit buildup.

That's the stuff and that is my plan, every 10k or right before every other oil change.

I was just curious how many people do it that often.

I never do it. I only did one injection cleaning just to see if there was a difference, there wasn’t. Never did a front end alignment either. Our roads are pretty good. My wife’s 12 year old car has never been waxed. I only did quick detail twice. It still looks new. My 02 avalanche I did my hood and roof with quick detail twice. Although I have to do the plastic panels 3 times a year. I take care of my vehicles, I don’t like to waste money.

I have never done it either. Top Tier gas only and fuel system cleaner when I think of it.

I do it on both GDI engines cars, 17 5.3L Silverado & our 15 X5 3.5L. This treatment only removes a small amount of the carbon on intake valves. Although I feel it's one of the better Chemicals out there with largest amount of PEA. Several video's on YouTube showing the results.

      Is 2027 GMC Yukon Getting a 682-HP Supercharged V8?

      By CaptPat51 · Posted

      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 network keep alive.

      Brake Pad Warning Message

      By Vu1can · Posted

      TrueBlue...Even if you don't have that info stuff displayed, If Mr. Computer thinks there's something you should know about, it will pop up a warning message no matter what else is being displayed. I keep the speedometer displayed all the time, yet the brake pad message pops up anyway.

      BTW, the 11.5amp draw is all the usual systems active - it's not a single draw - that's the "we're all awake" state of the vehicle - forinstance if the power steps are actuated, the draw will spike to 22amps for that operation.  when the battery is disconnected and then reconnected, the vehicle shuts down that one time only - and we see a 10-15minute progression down 11.5  10.5  9. 8 6. 5. 1.6... 500ma... and then off to sleep at 40 milliamp... as expected.  So we know it's a module that is simply refusing to allow the SDGM to proceed to the sleep state.  We do NOT think it is the telematics VIM module - since we already duplicated the problem with the "VIM bypass" solution installed (we reverted that since it also disables the gmc app - but it does not appear that the telematics system is the culprit).  We've replaced the rear heater control module, tested without the wireless charger, and the other modules on CAN Bus 5 - but still something is keeping us awake and removing X2 from SDGM allows sleep to proceed.  We cannot diagnose from OBD since OBD drops off at about the 9volt level in sleep mode and we can't communicate with the vehicle - also we can't trace the SDGM internal packets from the OBD side - we have Autel Ultra.   Any ideas on why disconnecting X2 would allow sleep to proceed appreciated.  This is no longer a repair situation - this vehicie is simply unusable in this condition and NOBODY at GMC Dealer can even understand what it is doing.  This is crazy.  We made these systems too complex and now we're paying the price.

      Did this ever get solved?   I'm chasing 2021 Yukon Denali electrical issues - vehicle will not enter sleep mode - we can disconnect and reconnect the battery and it will sleep - but that's likely because we powered down whatever module doesn't correctly sleep.  once we start/accessory the vehicle and turn off, it will stay at 11.5 amp draw with something keeping the SDGM alive - it appears to be activity on the X2 segment, specifically CAN FD Bus 5 - but we don't know which device and we think we've already isolated all of the devices on that segment - so what keeps the BCM and/or the SDGM alive is unknown.   I don't yet have a packet trace from CAN 5 (and since this Global B we might not get much info from it) - but the vehicle has been down for 8 weeks and previously GMC Dealer was unable to resolve "kills battery" issues with this particular vehicle - so I'm at a loss - it seems to be beyond local repair capabilities - and the number of "telematics keeps vehicle from sleeping" posts indicates this whole architecture has major issues - I hate to say it, but we might have to install a battery cutoff switch on the front grill - one of those red boat switches - to turn off the vehicle.;)  Any pointers appreciated;)  I just bought a CAN FD interface and I'm planning to try Savvycan and Peak Can SW to triage this further.
