    2019 suburban premier 6.2 on a roadtrip, started pulling power over about 2500rpms. No check engine light

    Back in 2018 my son's 2011 scion did the same thing, no codes and the car would not go past 2k rpms. I changed out the coils and that fixed the issue. I don't think a 2019 vehicle would do that with out throwing a code.

    Possible Vacuum Leak, With Graphs

    No, remove the injectors and clean them your self. If the computer is detects more fuel than normal and it trys to adjust by adding more spark. This is telling me you definitely have an injector problem. This happens because the injector or injectors have leaked fuel into the cylinder, and...

    05 Denali Put in D for drive but felt like Neutral

    Sounds to me like it's the neutral safety switch where the linkage hooks up. They are known to go out. I've replace several though the years in my nbs vehicles. You may have thought the truck was in Drive and in reality it was in Neutral.

    Possible Vacuum Leak, With Graphs

    Have you ever cleaned the fuel injectors? I agree with @B-train, they need to be cleaned. Another thing you can do is remove the spark plugs and inspect the cylinder w a endoscopy camera for wet spots. https://a.co/d/fagyN9P

    What does the resistor do?

    No forward gears, but revers works after loud clunk at nearly WOT.

    Sounds like the tranny is gone, how long have you had that transmission? I've seen several videos from performabuilt and not sure I agree how they rebuild their transmissions. They don't upgrade all the components that are known to fail. What is the warranty those guys offer?
