    2020 Suburban RST

    As far as AFM delete does anyone know if there is a difference in the red vs blue Range Technology RA003? Is it only to match the interior lighting with Chevy being blue and GMC being red? Or do they slightly differ for another reason...

    2020 Suburban RST

    Thanks! That's more of the type of information I was looking for. As far as oil do you stick with the factory recommended oil weight or increase it to a heavier weight? I know there's a big debate over regular oil and synthetic but for these engines specifically does it lend any benefits to go...

    2020 Suburban RST

    I just purchased a 2020 Suburban RST with the 6.2L engine and 10 speed transmission with 85K miles on it. I was just wondering what things I should be looking at maintenance wise to it. I am looking into the AFM delete but was wondering if there was anything else. I know the '21-'24 6.2L engines...

    Random Loss Of All Transmission Gears Including Park

    That's what I was thinking as well. I'm wondering if it's a transfer case encoder motor issue?

    Random Loss Of All Transmission Gears Including Park

    I have a 2005 Suburban Z71 with about 220K miles. I was getting off the highway on an off ramp and was coasting a little bit and when I got back on the gas the engine revved up like it was out of gear. When I got to the light I tried to switch to a gear that I could continue home in but I didn't...

    Towing Camper Trailer

    I knew those were the values but wanted to know what's more reasonable. The 80% that you mention sounds good.

    Towing Camper Trailer

    Hey guys I've got an 05 Z71 Suburban and we are looking into buying a camper trailer. Looking at ones that have all hard sides (not a pop up or hybrid). I was wondering what's a good gross towing weight not to exceed to not put too much strain on the drivetrain/engine and what length trailer...

    Service 4WD Message

    I thought there were ways to diagnose it without having the codes read. These are the ones that can only be read by a TechII right?

    Service 4WD Message

    I recently bought a 2005 Suburban Z71 from a private seller. I test drove it when I bought it and the 4WD was working at the time. Beginning last week, I randomly have been getting the "Service 4WD" message. I was in an accident that totaled my prior 2006 Tahoe Z71 and the 4WD always worked no...

    Bilstien Shocks to go with Leveling Kit

    Thanks. I’ve got the Rough Country ones in now that come with the leveling kit and they just seem to give a very stiff ride quality. I can feel every bump

    LED High Beams

    Was looking to put Depos on my 06 Z71 with my 35w hid’s. I’ve read LED’s are a good upgrade for the high beams instead of hid’s. Was wondering what people do for LED bulbs for high beams

    Bilstien Shocks to go with Leveling Kit

    I have a Rough Country Leveling Kit on my 06 Z71. I read on here people saying Bilstien shocks to go with a leveling kit but can’t find it again. Was wondering what model Bilstien shocks people go with

    Second Battery

    For those using an isolator, how did you connect the larger gauge wire (in my case 2 gauge) to the main battery that is side post? I know the top posts have those nice adapters that split off nicely but I'm having trouble finding something like that for side post.

    P0446 Evap Code

    Thanks everyone for all the info. Turned out to be the rusted fuel line on top of the sending unit for the fuel pump was leaking. That was causing whatever other stuff to misread and give the code. Replaced the fuel pump this past weekend and no more code

    Fuel pump replacement time

    I got the $150 rockauto fuel pump and just installed it this past weekend. If you are in an area that gets rust, I'd recommend picking up the fuel line connectors with the repair line kit that comes with the new connector attached to a new fuel line section. With a 1/4 tank of gas left in the...

    Cluster bulbs

    If you are looking to change colors and upgrade to LED's check out my thread should answer a lot of your questions. I found out that 04 can go either way being twist in bulbs or bulbs that you have to solder in.

    P0446 Evap Code

    Thanks! I’m planning on dropping the tank and doing the fuel pump along with the sending unit. The evap code went away so I’m wondering if it’s only when the tank is full

    P0446 Evap Code

    Was looking at it some more tonight and noticed there’s fuel leaking from the top of the gas tank in the back. I’m guessing it’s coming out by the fuel pump assembly. Wasn’t sure if it’s actually leaking or if it’s leaking due to the pressure caused by the evaporated canister or purge valve

    Dimmable LED Gauge Lights

    Anyone do (or have a picture) blue LED's with red needles? Wondering how the lighting turns out with the red and blue

    P0446 Evap Code

    I changed the evap canister on the back of the fuel tank and the purge solenoid on the intake. I’m assuming that’s the one you’re referring to. Do they still sell the non updated one at Advance Auto? I got the AC Delco ones. The one thing that is leading me to maybe a leak is the strong...
