    2005 5.3 Tahoe running rough/stalling only when hot

    Have you looked at the temperature sensor...might be off enough to tell computer it's cold when it's not and subsequently making it run crappy when hot.

    New cam and higher # injectors?

    Your injectors are fine, don't mess with them unless/until you turbo or supercharge it. With a super mild cam you'll be fine where you are.

    How to: EGR Delete, tube block off.

    I just used a freeze plug, forgot the diameter exactly but you can measure it. Its a good fit, I just smeared a bit of rtv on it. Looks good and doesn't intrude into the throat at all.

    0-60 in 14 seconds?

    Yep, should be considerably faster than that for sure. I have the same thing. Keep digging you'll find something. I obviously don't know the history of yours but, maybe cats are clogged or melted.

    My '02 Tahoe L59 revs WAY too high on cold start ups. Anyone got any ideas?

    I'm with the guy that earlier asked about vacuum leaks, specifically intake gaskets. Was a known issue on at least the 01s and I suppose the 02 as well. I experienced the same thing. The colder it is the worse it would get, once it warmed up a bit you would never know...If they are original...

    Front brake upgrade from 2013 Avalanche?

    I put fronts from a 2013 suburban on a 2001 tahoe...calipers bolted right on. No brackets required. definitely worth it and by the way you'll need the rotors too

    Uneven Idle is getting progressively worse but cannot find the cause (Fuel Pump / Injectors?)

    I'm thinking vacuum leak, he could rev up the motor and watch the short term trims and see if they drop...if so he likely has a leak. If he can't actually visually find anything he might need a smoke machine.

    Boost options for a 2001 Tahoe w/a 5.3L?

    I don't know about the 4l60 crapping out before 200k...I have one tahoe with just short of 300k on it, another with 190 on it and yet another with 250 on it and they all are original and work like new. I guess guys who never change fluid may problems but, taken care of can last longer than 200k

    Engine Failure on New 2021 Yukon AT4

    That's freaking stupid, why gm didn't give up on the afm/dod stuff years a go is a puzzlement....it just gets worse and worse. hard to beat a lm7 for reliability That said, I just read that they are not activating the dod on the latest trucks because they don't have the chips to operate it.

    Where did you source a new DASH?

    After looking at all the gmparts guys on the web and seeing their outrageous shipping cost, I went to the local dealer and got it for the same price with no shipping cost. So I saved a couple hundred or whatever it was. That said, I don't know the current price but have noticed a dramatic...

    TVS or Whipple on 5.3?

    Can't argue with that. I did talk to the whipple guys and they said I could go down the 1 size being that I run 93. Their tune is for 91 with PE at 1.280 That said I am still nervous about a smaller pulley without checking it out as you suggest. Edit: I also remember Kenne Bell saying the same...

    TVS or Whipple on 5.3?

    Just ran across this thread, I have a 2013 5.3 suburban with a whipple. Not jumpy at all, runs great with the whipple tune though it's definitely a conservative tune. I only have done two 0-60 runs and got 5.75, haven't done a 1/4 mile yet but will when I get a chance. on a good day could...
