Fuel pressure increase when in open loop due to CEL
In the grand scheme of things, if your goal is to sell the vehicle, I'd just get new (parts) from rockauto (or wherever you get your parts) whenever you find out what the issue is. Given the history of the AFM in this vehicle and your poor compression readings on that cylinder, I'd venture to...- TSOL

2013 Suburban with very light misfire at idle and highway speeds
I checked my O2 sensors when idling and they both swing rapidly from 0.1 to 0.9V. A quick Google search shows that this is exactly what they should be doing. I'm gonna see if I can find a way to test my CASE values.- TSOL

Fuel pressure increase when in open loop due to CEL
Yes. Mine does that exact same thing. I have 43 PSI closed loop, 58 PSI open loop. I have 2013 Chevy Suburban 5.3L V8. Misfires are typically due to spark plugs as far as I've seen. They have plenty of other causes, but these are by far the most common and a great starting point. Have you...- TSOL

2011 GMC Yukon Denali makes a thump noise upon take-off
Is it just on take off? Do you have any other symptoms? Our old Suburban had totally shot U-Joints (couldn't tell until they were removed) that caused a clunk every time you put it in foward or reverse. It also caused noise and dash vibrations at 50-60 MPH. Not above or below that though, oddly.- TSOL

2013 Suburban with very light misfire at idle and highway speeds
I have been watching my ethanol every time I've gotten in the car. I drive 1h30m daily to work, so I refill twice a week. I've put probably 3 fills of gas into this suburban (I fill at half tank) and the ethanol content hasn't gone up. It has gone down actually, it now reads 0.0%. I talked to my...- TSOL

2013 Suburban with very light misfire at idle and highway speeds
Hello I have a 2013 Chevy Suburban with 215k miles and a very light misfire at idle and highway speeds. The misfires are so light that I wonder if I'm blowing it all out of proportion and its actually okay. Some important info: 1. The check engine light does NOT come on. The misfires are found...- TSOL
