My stock '04 runs a bit over 40psi at cold idle, and around 30-35 hot idle. Easily over 40 at highway rpms.

I have a 2005 Yukon 5.3 and had the same issue but I had some lifter noise also. Ended up replacing the oil pump and fixed the issues. 292k miles and still going.

Different engine completely. That’s perfectly normal for yours. The NBS run quite a bit higher normally.

Are you sure? I just notice 2 days ago that my AFM works only when coolant temperature is bellow 210. I made some research and found that oil pressure should be in the range of 27-66psi To enable AFM. On my 2010 Tahoe, I also have around 20-22psi oil pressure at idle or not accelerating and 30-40 when accelerating when motor is hot. It doesn’t look normal . I will try to change the oil sensor filter which looks to be a problem on this engine. I got this Tahoe since few time, mileage is 100k but I‘m really not sure it was well maintained since 3 years because I don’t have any maintenance reports paper or carfax info since end of 18’. I will also change oil , oil filter to be safe
Yes I’m sure. Also, AFM doesn’t activate at idle so the pressure at idle has no effect on it. 20-22 at idle is normal for your truck. You can do more research if you feel I’m in error though. There’s tons of info on this.
