    2004 tahoe whining not serpentine belt tensioner or idler pulley

    have you checked the power steering fluid level?, has it ever been flushed? generally the power steering pump or alternator are the only things that will whine some (not necessarily squeal unless they are on a last leg). ac pump's tend to sound like a bucket of bolts being chewed up by a wood...

    Yet another crank no start...strange

    I would start at the battery and grounds, you could have spark but not a good ground. or also check the ICM (ignition control module) that one is a classic problem, if that is bad everything else will be fine but it won't run and they tend to die out of the blue

    Engine Revs up and down at 35 to 40 mph

    I would be inclined to say if the rpm is fluctuating and you cannot feel or see a direct correlation in speed, then I would be pointing my finger at the transmission there is no other logical reason, if it's running like dogshit then you would feel it, if the rpm gauge is floating around with no...

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

    so the KA units do not receive vehicle speed data from a hardwired source? seems like if it was self-determining vehicle speed that it would make it happen consistently, but this was very random also the thousands of other times I have been in front of or behind ka it's only happened a few times...

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

    yep, after about 10 years these are prone to break at any moment. I replaced mine at about 7 years to hopefully avoid this issue if you bought the Dorman, no telling if it will last as long or not.

    ELM327 OBD Bluetooth Diagnostic Module That Can Scan Other Modules Such As ABS, BCM, TCM?

    that's sort of what it does when you add another key, they all have to be done together and any pre-existing key not re=programmed with them at the same time will no longer work.

    96 Tahoe, Need 12 volts when cranking

    just look up fog light relay wiring diagram on google there are tons of examples/diagrams, it's pretty easy to do. It should fit right in with your existing mods. I wire HID's this way because they draw a lot of juice and they tend to work crappy if not wired up with relays. sometimes factory...

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

    this was KA, they stopped using x/k here years ago, although the next town up is cheap there city pd still used k band at least up until about 10 years ago I think it was more possible he was switching front and rear on/off and my detector was picking it up as such. that's just my guess

    96 Tahoe, Need 12 volts when cranking

    I am not personally "real" familiar with the aftermarket ignition that has been added but you could connect a relay directly the to the battery and controller and use your crank signal as the trigger, that would ensure 12v is going right to it. check that your grounds are clean and good also.

    2015 Yukon Denali XL

    i am always skeptical of internal engine work myself and why it was done. have you gone and looked at it? when you do ask for the service records and see what the paperwork say's, if it was done by a dealer it will have the reported issue, diagnosis and what was replaced. besides it is a 2015...

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

    ya, every once in a while someone will try to speed up but then there is that challenge, if they are doing a good clip I will back off but will still pass as soon as I see a opening. I caught up to a highway patrol once before and he was doing to a pretty decent pace, I wasn't riding his ass but...

    ELM327 OBD Bluetooth Diagnostic Module That Can Scan Other Modules Such As ABS, BCM, TCM?

    that's not what I mean, the security on the k2's is leveled up with no programmed key at all it requires a certain procedure with 1 programmed key it requires a different procedure to add another key with 2 programmed keys it is like the gmt900's, which is easy

    What alternator years are compatible with a 94?

    take a picture of it so you can compare it to a replacement, junkyard should know the crossover years and makes and there locations.

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

    he got me, I can't deny that and apparently they are targeting that area because I have seen 4 cars pulled over in the exact same spot since then, basically each time I drive thru there. I need to slow down anyway for the time being. just drove 4 hours, 2 of them thru tight twisty hairpin turn 2...

    Front Driveshaft bolt size

    I didn't read this correctly at first, you can take a existing one to a hardware store and get the same length pitch & thread. or if you want oem or a "set" most likely you will have to order them, nobody seems to stock them.

    Powerstop K6560-36 vs Detroit Axle Drilled/Slotted Brake Kits

    this set will run you about $450, can't beat it unless you go up to a big brake kit most of your other brake calipers out there are "remanufactured" even the powerstop rotors are from "oem samples"

    Beam lights turn on in the dash when it rains

    I do not have a 21 but sounds like the automatic headlights are coming on, around here that would be a good thing since if it is raining your lights are required to be on by law

    2004 GMC YUKON KEY IGNITION PROBLEM

    normally you have to turn the key to run and push the pin hole (under the plastic cover) to remove the ignition. They have been like that since the 70's maybe longer

    2018 GMC Yukon SLT 4WD wobbly

    usually the shocks are replaced in pairs because if one is worn out and leaking the other will be soon if not already. use a spray bottle of soap/water mix and check for leaks. (bubbles) be sure the pump is working. the shocks should hold air for weeks without the pump being ran, so if you check...

    I have had that tool for years, pretty sure it has saved me a few headaches I believe mine is the more beefy 1/2" version though

    For those I use one of these, actually the older version, you just smack it with a hammer and it "hopefully" breaks it loose. always has worked for me
