    2012 Yukon XL Spark Plugs and Wires

    I feel like the idle still has some random dips in it. This was happening even before I changed the plus. It idles around 500rpm but ai feel it dip ever so slightly but it never stalls out. Is it typical for a Yukon?

    2012 Yukon XL Spark Plugs and Wires

    Changed my plugs and wires on my 2012 Yukon XL. I don't think my plugs were in horrible shape but being that I just bought the truck with 136k miles, figured I start with fresh plugs. Picked up some NGK Iridiums and BWD Wires. Surprisingly, the install was incredibly easy. Even getting to spark...

    Let Me See Your Tahoe, Yukon, Or Denali!

    New to the forum. Great to see a variety of trucks out there! Purchased this 2012 Yukon XL SLT 1500 with 136K miles for $13K. It has many factory upgrades on it such as chrome package, towing package, air leveling suspension. Even with the 26" rims it drives a lot better than I expected.

What is the best method to remove the Service Suspension System message when the ride height is changed due to larger rims? I found these adjustable rods on Ebay. Any pros and cons...

    2012 Yukon XL SLT Service Suspension System

    TPMS problem solved. This set of wheels were on a different Yukon at the dealer and they swapped them onto this vehicle. Tried the manual learning process in the manual but I guess since the sensors were adapted to a prior vehicle they have to be reprogrammed? In any case, bought a $10 GM...

    2012 Yukon XL SLT Service Suspension System

    Just purchased a 2012 Yukon XL SLT with 136K. While test driving I didn’t notice a Service Suspension System with the stock rims and tires. During the purchase I requested aftermarket rims and tires (26”), which got installed while I waited. I finished the transaction, left the dealer, got gas...
