    Ride Quality

    I have a 2013 Denali Xl with 287k on the clock. To my knowledge it still has the original shock/struts. I seems like you feel every bump and crease in the road. I am looking for a more comfortable and smoother ride. Any help appreciated.

    Stock Rims issue!

    I have had them use a wire brush with rotary wheel a couple of times already, not sure if used a sealant or not. I was looking to pick up a set of factory 20s off FaceBook or salvage.

    Stock Rims issue!

    I have a 2013 Denali XL that has the stock 20 inch chrome rims. They are peeling a fair amount. The real issue is that due to the corrosion and peeling the will not seal and therefore leak. I have had them wire brushed a few times but it has not changed much. My question is do they make a...

    [SOLVED] USB port issue?

    I have a 2013 Denali XL. In the past I could hook up a iphone 13 pro to the usb port in the console and hit the ipod button on radio and It would play my music. Now it will not work. It always says "driving restriction prevents screen display" when I cycle through the sources. Using the same...

    Misfire problem

    Yes it does have AFM (total crap} Yes to injector balance test. Has checked harness, manifold bolts and I don't have the number but fuel pressure was good. He has not been to come up with anything. Says he could go further in with some new lifters etc but was not sure if that would be the...

    Misfire problem

    I have a 2013 Denali XL 6.2L with 285k. About a month ago I was going down the highway and all of a sudden it started to really miss to the point it would hardly run. I scanned it and had multiple misfires. I had it towed to my mechanic. He has checked lifters, swapped coil packs, swapped...

    2013 Denali poor acceleration

    Fuel mileage really has not changed. I don't think the scanner does alcohol %. Always using regular gas. I wonder why it has never thrown a misfire code? Once you get above 1500+ and stay there......no problems. When you slow down and try to accelerate gradually it happens. Almost like the...

    2013 Denali poor acceleration

    I have a scanner by foxwell. Fuel press at the rail is in the 40's. The fuel trims are all approaching zero. I was thinking of the throttle body position sensor but wouldn't it throw a code?

    2013 Denali poor acceleration

    Update, I changed wires and plugs. One of the wires was broke. However it never did throw a misfire code??? It seemed to run ok for a couple of days. Then it went back to previous symptoms. It runs fine as long as you are giving it throttle, like on interstate or accelerating. But when...

    Media not supported?

    I have a 13 Denali. I have been using my iphone 13 pro by plugging it in the console usb. It works and sounds great. However when I try to use my wife's iPhone (same model and iOS version) it says media not supported. Any help appreciated.

    2013 Denali poor acceleration

    2013 Denali XL with 250k. Upon cold start there is some rough idle and missing when accelerating. It seems like it even affects the shifting. I found p0172 & P0175 as well as p0101 (mass air flow). I cleaned the MAF and the dash light went off and it seemed to run much better for about one...

    Knock sensor P0328

    Sorry for late update. The place or person that did previous maintenance on the vehicle did not do a good job. The motor mount was replaced but was not tight and they pinched the knock sensor harness wire. I installed a new one and now that problem is solved. Thanks for all the help here!

    Knock sensor P0328

    Thx for the reply. Does anyone know the part number for the AC Delco harness? RockAuto doesn't carry it. On their site it says the AC Delco sensor mates with PT2652 but when you look that up it says doesn't fit your vehicle. RockAuto carries a Standard Motor Product brand of connector.
