    OPEN RECALL

    I got my recall done the week the original notice was published. It's an absolute tragedy that so many people died in Rangers / Civics because owners were too lazy to get the shrapnel filled airbags replaced.

    low oil PSI when passing

    When our trucks came from the factory the oil pressure gauge sat 40 PSI at idle and would move up to 60 under acceleration. You've already unstuck a lifter so more than likely your engine is on the way out. You can replace your Oil Pickup tube O ring and even the oil pump but you're at the...

    2009 Yukon 2WD; New metal-on-metal sound from front end.

    If you want to make it exciting you don't have to pull the wheel / fender. You'll cut your hands up a bit but when I had to do mine on the side of the road it worked.

    Rough idle/ shuddering in idle.

    If the misfire is on the exhaust side lifters I don't believe it throws a CEL. I've tuned my truck to a higher idle to reduce the rough idle but I'm fairly sure there's an issue with a lifter / the cam on my exhaust side which is why I never get a CEL

    Uneven Idle is getting progressively worse but cannot find the cause (Fuel Pump / Injectors?)

    Raised my idle and it helped a ton but it's still there. I've basically accepted it until I feel like doing a full tear down to discover the issue.

    Diablosport Trinity T-1000

    Diablosport Trinity T-1000

    thinking of buying an 09 yukon xl

    According to the 2009 Brochure: The trailer weight is 5400 2WD and 5700 4WD. If that Tahoe has the Heavy Duty Tow Package those numbers move to 8,400 and 8200. So it's going to depend on your needs / if this Tahoe is optioned with the Tow Package.

    Idle Oil Pressure Thoughts (Currently sitting at 20 PSI fully warm).

    Used a DiabloSport to increase my idle by 150 and it feels like I'm driving an entirely new truck. I think I still need to tackle the oil pump at some point, but the change is pretty dramatic.
