    Probably need new O2 sensors?

    hopefully it goes well. I got the clamp on mine and hoping I never have to replace it till the day the motor comes out haha

    Probably need new O2 sensors?

    it's a after cat o2. less important, shouldn't effect a:f. the manifold leak will thou, they suck in air and make it look lean so the ecm adds fuel. I'd say fix that first. if the bolt I'd broken off, they sell add on clamps to seal it up. clear code and go from there.

    Cooling fans coming on max after cold engine start, stays on till engine shutdown

    At least on mine, use tech 2 or others can see both low and high side pressure. I still fill like something is defaulting the fans on. like I've forgotten to plug the temp sensor in and it turns the fan on max any time it's running. he's replaced it thou, maybe a tranny temp sensor?

    2009 hybrid tahoe w/ 140k miles....... or 2014 tahoe lt w/ 170k miles... which would you take?

    I'd buy whatever is a cheapest beater car local to you, say something 500-1000$. fix your truck and then sell the car for what you paid. if you're stuck on those two trucks, it's a toss up to me. the 14 at 170k the converter in the tranny is about ready to lunch the whole thing if it hasn't...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    seems like I remember the v6 was the 3.1? actually wasn't bad for it's time. the iron duke was legendary for its lack of hp. I had one in a 86 Cavalier someone gave to me and we used as a beater car for a while. couldn't hurt it.. but man it was slow haha. it drove itself to the junk yard years...

    Bigger brakes for GMT900 short of a C6 conversion kit?

    I have baer erradispeed on my c6, well it came with them when I got it used but I can say they are some quality parts.. many mountains trips/runs, 2 track days.. killed a set of hawk pads at both track days and melted the plastic center cap out of the rim the 2nd time, and that's with brake...

    Cooling fans coming on max after cold engine start, stays on till engine shutdown

    there might be some other codes besides the P codes in the ecm. not all scanners can read them. like my truck has a few codes for seats motors that will only show up on a scanner that can read all 30 sometimes modules. besides that, I got nothing useful to even guess at

    Cooling fans coming on max after cold engine start, stays on till engine shutdown

    you can read the high side ac pressure with most scanners, even torque app. the low side takes a bit better scanner it's under the hvac live data. atleast on mine. bag high side pressure transducer isn't a bad guess. would probably have some hvac trouble codes if so, but that takes a good...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I got a racing on highway ticket in my early 20s, really it was a dead end back road at 3am in the middle of no where. not highway involved. on my record with the fbi got life, comes up every 2 years when I got to renew my badge. considering criminal not traffic. blah.

    07 Escalade 6L80 into 12 Escalade - swapping 2012 valve body/TCM into the 2007 6L80

    I think I remember @nickstransmission saying if you transfer the TCM over you don't need to reprogram, but I'm also guessing that tranny has to match the TCM you're putting on it. and I don't anything about that side. if you need to reprogram, it's not the end of the world.

    Engine Used Oil Analysis Report & Filter Guts

    yeah, funny thing that. fram now makes good filters, on the level and even some applications off the same line as the Amsoil filter and the wix lags behind most as far as micron ratings go. the days of the old orange 2$ fram being the cheapest worst filter on the market are long gone. but...

    2008 tahoe p0300...

    do you have any broken exhaust manifold bolts on the drivers side?
  16. J

    2008 tahoe p0300...

    so drivers side is adding 25% fuel, passenger side is removing 25% fuel. gotta admit, I've not see that one. feels like swapping o2 sensors side to side and see if it switches might be a thing to try or if you have to money just replace both. they are considered a maintenance item.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I think the dioid dynamics fog lights are the thing. pricey but I have a feeling being so low they are more useful than the headlights on low without the worry if blinding on coming. I don't have them, I went with a bi-led in the fog, even though the light output is amazing. I wouldn't recommend...

    Engine and gearbox swap from four speed to six or eight speed on 2008 Z71 ?

    4L60 gets a bad rap but the one in my obs was solid. truck had 325k on it, I put a good 150k of that, I was told it wasn't rebuilt when I got it, but who knows forsure. I know they don't hold big power well and don't like to tow in overdrive. but stock for stock, with just fluid changes by the...

    2008 tahoe 5.3l afm/dod delete issue

    if you have one handy, you might do a compression check on those cyl before throwing money at it. Just incase I've used this way to check an injector is working before. it did a good job of opening one up that wasn't spraying much. never tired it on one that is wetting cyl down thou...

    Universal Remote System: Can It Be Re-Wired to Ignition or RAP for Its Power Source?

    I know 2 people that's use cameras like this.. not 100% sure it's the same brand and they don't have the opener option. but my only concern over the cheap 30-50$ home cams, especially the ones that don't charge you is most people don't realize there's gotta be a server behind all this, almost...

    Universal Remote System: Can It Be Re-Wired to Ignition or RAP for Its Power Source?

    I had a friend in FL that was adamant about the same thing. left everything unlocked till eventually they walked up and went thru his unlocked car, open garage and looked in his house but didn't take anything in there while he was asleep in his bed. dig finally woke them up and he ran down the...

    Universal Remote System: Can It Be Re-Wired to Ignition or RAP for Its Power Source?

    I could only get my newer car to work with my opener, sad too because the last owner definitely put new openers up and nice doors in before we go it. Just one model before wifi. the 2011 yukon or 08 c6 couldn't program, only my 14 car. so keeping remotes in them was a worry. we get random rashes...

    08 Yukon Aux Trans Pump Module Issues

    so here might be the confusion. there's 2 part numbers only 1 number apart and they both look almost the same, but I think one is tranny side one is harness side. 24259588 and 24259589 if you open both pics side by side they arw different adaptors. Disregard 24259590, I think that's...

    2008 GMC Yukon Denali - Stay away?

    the 15 and 16 are direct injection LT I believe right? totally different engine to the older Gen 4 6.2. but I don't own either, just what I read from here and the owners manual. I have an aluminum 6.0L designed to run on 87. cracked ring lands and stuff after 120k miles or so on 87 is what I...
