    The tech2 I said I had earlier, that is the correct one to use? Not sure what I'm checking to check front shock stuff, the connectors are just laying in the engine bay (not connected at all)

    Ok, I'll get on that. Hopefully it just needs the compressor Is there a way to test the front setup, or do i need to just buy a pair and install to see what happens?

    Right, I'd like to if that is a feasible option. The height sensors seem to be reading with the tech 2 (the numbers change if I move the vehicle around), so those are working i guess. however all the dampers show 0%, and the compressor does not turn on or off with the tech 2 (it says off, or on...

    Apologies. I was asking if the bad sensor could affect the suspension. I definitely do not hear the air compressor turn on. I'll go underneath and have someone turn it off/on, to see if I can hear anything. I just don't want to buy a bunch of parts to find out it has a bad computer, or wiring...

    I have a tech 2 I have a new wheel speed sensor that the tech 2 says it needs. I think it's the pass rear sensor. Would this cause it to not activate? How audible is the compressor?

    My yukon needs front/rear suspension work badly. The rear air shocks are blown, the front shocks don't seem to work either. 168k miles on the truck. Is there an easy way to troubleshoot this? How loud is the air compressor(As far as I can tell I've never heard it fire up? I would like to just...

    Oil pressure is still pretty low in gear with hot idle (500 ish rpm). Probably 13psi? Runs great now though. 168k now on it Wife is wanting to use it now, so I need to actually fix it (was just using it as a back-up vehicle as we have 2 others and I have a company car). Need to fix the...

    I did fix it. Not sure if it was just the oil presure dropping too causing some kind of issue (vvt maybe??), or the TB (I gave it a thorough cleaning). Fixed a damaged pcv hose as well.

    I put that 917-107 clamp on. I need to get a new gasket to see if it actually helps. Pretty neat item! Will headers or y pipes that fit 5.3/6.0s also fit the 6.2 or are they different?

    anyone know of some decently priced headers/ypipe/exhaust type setup? longtube or shorties. not looking for a huge perf increase, think I need cats. I'd be ok with a y-pipe that bolts up to the factory location as well (with no cats, or high flow?).

    thank you. the 917-107 seems like what I would need(pretty neat too!), but does not show it as fitting the 6.2 for 2007. does not seem to be leaking from the broken bolt location however (pass side front bolt).

    Put new plugs in today. It was wayyyy over sure. Average gap on them was .080"! Pass rear plug was a little difficult to get at, but removing the wheel well liner made it pretty easy. Found it has a broken exh manifold stud (front one) on driver's side.... Bummer! Next up is driver side abs...

    Photo of the buttons. I believe your are correct. Button doesn't do anything. That's what the disconnected wires under-hood go to?

    replaced my pcv clean/dirty lines. seems to have helped with my idle issues (would hang a little when driving). they were cracked pretty bad and leaking a lot of air.

    I've been playing with it some. But there is a lot of stuff, and I don't know all of the acronyms etc haha. I've gotten some of it down. But there's quite a bit more I need to learn. Best tuner that I can use on the truck? I'd like to eventually get a tune for it, but for now just so I can bump...

    both my 'fresh air' pcv valve hose, and my 'dirty air' pcv valve hoses are cracked etc. The dirty air one i can actually hear sucking/blowing air, if I fiddle with it it stops. I seem to be able to find the 'clean air' pcv one pretty easily online. The dirty air one I am struggling to get a...

    Replaced the valley pan and vlom orings(original ones were quite flat), intake manifold gasket, oil pressure sensor. Zero change with my oil pressure when hot at an idle. Not sure what else is left other than trying a quart of lucas. Oil pump i guess. Doesn't seem like it would be that to me...

    I'm planning on replacing the swaybar/swaybar bolts. Right now theres nothing there at all lol, just the busted bolts. BTDT as well, I'm from up north. Love living down in the south, where my 16 year old vehicle with 170k miles isnt a rust bucket lol. I just took my exh manifold bolts out with a...

    I got Alldata diy and from what I've seen in there that 1 large connector seem to be a suspension relay. the wire next to it is the one in my photos i've posted that looks melted. Thats probably why it doesnt have active air anymore. Is the rear air/front air tied together? Or do they operate...

    changed out exhaust manifold gasket, plug wires, valve cover to new style valve cover/gasket. drove it about an hour today, lowest I saw oil pressure hit was about 13psi in gear/idling at about 550rpm. still see close 35-40 psi at about 1100 rpm cruising going to do the intake...

    anyone have any input on those front shocks, or what goes behind the fuse box in the engine bay? @Geotrash

    about to replace my exh manifold gasket, as it has a leak. looks like oil from valve cover has been leaking on it. I'm seeing posts about replacing valve cover and not just new gaskets/orings. Not sure it applies to me though? Going to be doing exh man gasket along with valve cover gasket (or...

    so if he is correct, it wont stall anymore. it didnt always do it without fail... so I need to drive it some to test it. It is not my daily, it will take some time before I can drive it long enough to test it.
