    Random/Intermittent No Crank. halp!

    If the starter doesn't work out, I would be highly suspect of a bad battery to block ground cable. try connecting one black jumper cable lead to negative battery post and other end to block next time as a test bypass.

    Misfire Issue when it rains

    yeah, the spray test is just to show if spark is jumping out...wont show problem with wires to coil connector..except maybe to cause a misfire...need to check coil signal wires in harnes and i believe each bank has common ground...you can try splicing into one ground wire with a piece of wire...

    Misfire Issue when it rains

    hmmm...at this point i would check the integrity of cyl 6 coil connector plug and the 4 wires i believe it has feeding into it. you may have to take some tape off and see it there is a chafe...perhaps seal up where wires enter connector with some sealant..from your symptoms....fine when...

    Parking brake (yes, another one!)

    Ahh, i see. Well, the loose cables are a common fail so hopefully it will help others that end up on this post tracking that problem. Good luck on your quest. I had it and my co-worker had it and spacers tightened things right up.

    Parking brake (yes, another one!)

    My money is on loose cables..there is a fix in forum post link below. it utilizes a spacer to allow more travel of rod/cable through adjuster bracket under bottom of truck. a stack of nuts with an inner diameter large enough to slide up and down threaded rod will also work in lieu of spacer...

    Cold Air Intake (CAI) on 2013 6.2L - worth doing?

    yep, from all the research and reading i've done...the best bang for buck on these is a tune...from factory the box, exhaust, heads, are all really quite optimized already for average guy like me who stays in low rpms most of time

    Misfire Issue when it rains

    swap the 6 coil and wire with cyl 4. if problem moves you have a coil or wire issue. if so, switch wire back to 6..if it returns back to 6 its the wire. if it stays on 4 its the coil.

    Yet another Yukon with engine tick and low oil pressure

    yes, check for exhaust manifold tick if its developed a loose spot...has fooled many folks if not, also, my 2002 liked an ac delco filter better than wix and mobil for start up sounds never thought it would make a difference but it did...

    Code : P2A04 Oxygen sensor question

    yes, the two rear are inconsequential to engine performance, but will throw a light when they decide to go lazy...at your mileage now I think its a good call to knock out all four as you intend..

    Code : P2A04 Oxygen sensor question

    Code : P2A04 Oxygen sensor question

    good plan..soak them all down with pb blaster while they are a bit warm after a drive and use a 7/8 or 22mm to turn each just a bit tighter..yes tighter...this will develop some hairline micro cracks in the threads allowing capillary action to pull in the pb. the next day things will go a lot easier
