    Intermittent tick starting, what you think from the sound?

    Its very normal My 04 does the same thing…after about a minute it quietens down. I thought it was oil not at the lifters and once you run a minute its lubricated. I was going to try lucas oil stabilizer added to the oil and see if that helps but hadnt made it a priority. On cold days the noise...

    Yet another Yukon with engine tick and low oil pressure

    Go somewhere else and dont trust a person that says you need an engine when the lifter is bad thats very low knowledge of how this works. My dad had the same thing on his 6.0 and drove for about 2 years and locked up the motor but it was a lot lot worse than this. he could have fixed it by...

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

    I wasted money on my 04 with a k&n cold air intake. I can tell you calling this cold air compared to the factory one is a scam. Maybe less restrictive i could see but it makes you hear the motor sucking air more which some people like that. Its really a waste of money for an inferior product...

    6L80- Drive it till it quits, rebuild local or replace with rebuilt GM part?

    The gm 3 years/50k warranty is a lot better and cheaper. These are remanufactured not refurbished there is a big difference. When you take it to a rebuild place they replace things that are broke and obviously warn out but if something tests ok they will reuse it. I think longevity will come to...

    Another Spark Plug Thread

    This is crazy but i have 225k miles on my tahoe and pretty sure it has the original spark plugs. I did buy it used 2ith 110k on it but the lady i bought it from said she had only changed tires on it and transmission had gone out and wasjust rebuilt. The plugs are 41-985…the plugs still work but...

    Not sure this is going to work out (considering selling after 3 weeks)

    How about getting a programmer and changing the way it shifts? I have a 04 and hated it for a while the programmer made a big difference in changing the shift points. Your tranny is setup for eco not fun. You could change that with a programmer. No idea abouut something that new but on an 04...

    4wd not working. AUTO 4wd works

    A lot of people say to get a tech2 scan and trace wires. Most people cant get one of those and too much trouble to be honest trying to figure out electronics. There is nothing wrong with that but although i have a degree in physics i am really simple minded. Another approach is to observe what...

    4wd not working. AUTO 4wd works

    Ditto, i have a 04 z71 there is no traction control on these. I am suprised your locker didnt activate. After 1.5 revolutions that rear differential should make a loud clunk noise and then the other rear wheel should start spinning. The z71 has an eaton locker in it from the factory maybe...

    Mine sounds like bacon sizzling on a pan. I can see the water dripping onto the heat shield of the cat.

    Dripping from tail pipe

    Hello i have a 2004 tahoe. It drives fine no codes but every once i a while i see a wet spot on the ground where the tailpipe is. I have never seen anything dripping but obviously it has because its pretty often i notice a wet spot. I want to say its just condensation but none of my other...

    99 5.7 4x4 Yukon Intermittent Run Issue

    Sounds like fuel pump to me it needs quite a bit of pressure to stay going. Do you keep your gas tank full? I have read that the gas actually helps keep the pump cool. I wouldnt think a leaking injector would stop an engine like this. It would sputter around for a bit. Maybe the fuel pump...

    [HELP!] Have you ever heard this metal on metal noise?

    I think you just have something rattling. Something got loose. A transfer case doesnt do anything when its sitting there.[/MEDIA]

    New owner, driving on sand AWD questions

    You will likely never have to have low range. These vehicles plenty of torque to grt you rolling. The wide tires will help also. I doubt a locker will help like it does on ice and mud where the road could have grip on some places but slippery on others. Sand is usually very consistent and...

    Wrenching in the gravel?

    I use either cardboard or the windshield shades to roll around on to keep gou out of the dirt/rock/mud…They are soft. The windhield shade is very slippery it suprises me how i can slide around under there. I would get a piece of 2x12 to put the jack on so it doesnt sink

    GM better come up with something better than their current engine lineups

    I dont like turbos. Sure they make a lot of power but i dont like reving them that high to get there.

    Transfer Case Issue

    I would take the encoder off and put it in 2wd manually and drive it around. If it drives fine the transmission is fine.

    Transfer Case Issue

    I have a 246 on my 2004 tahoe that had the dreaded oil pump rub through the case issue. I pulled all the gears out of there to put in the new case. Its pretty simple gear on gear not much to go wrong. I really doubt its the transfer case. If you really think its the transfer case and you can...

    08 Tahoe help!! Cylinder #1 misfire

    I would replace that plug to start with. Its cheap. Just because you put a new plug in there doesnt mean its not defective. If you have the old wire maybe put that wire back on at some point if you continue to have issues

    Think cats are clogged need opinions.

    With that many miles your over due. I fought the same thing at 150k. Replaced some sensors but it was the cats so wasted time hoping it wasnt the cats. I drilled a hole in the pipe before the cats and had a very sensitive pressure meter and they were not clogged. I stompped on the gas and...

    Help me decide?

    I didnt know they even put a disel in a denali….our lexus has the advanced cruise control…we dont ever use cruise. The rear view camera is nice but you can get these aftermarket if you really want it…emergency braking on our lexus is nice but no experience with this on a gm. Good luck on...

    Stuck in 4WD

    This is a shot in the dark but my 04 has had a lot of these issues did you try the start in reverse to reset all the controlers? On a 2004 turn the key to on but dont start it. Put it into reverse then try to start it in reverse. It obviouly wont start in reverse but it resets all the...
