    Oil Pressure Woes - Need Advice/Help

    Folks, I got a heck of an issue and I'm plum out of ideas. I need some help in the worst kind of way. Sorry in advance for the length, but context and details is how you get to solutions, right? LOL Bearing that in mind, I'll give the TLDR version first: My oil pressure sender has gone out...

    Need Some Parts Buying Advice

    My '07 Tahoe LT just rolled over 281.3k. Got a new long block around the 200k mark. It's a long story, but I need to do some teardown on it for a water pump and a rear main seal. While I'm in there, I really should replace all 8 coil packs, all 8 injectors, plugs, and wires (plugs and wires...

    What to Buy for a Tech 2

    I've search via this forum for quite a bit, and google for quite a bit more, but I'm kind of running into a wall, so I'm giving up and just asking. I'm broke, but so is my truck, so something's gotta give :) I need a tech 2 for my '07 tahoe, but I can't afford a tech 2. I'm trying to find the...

    Intermittent AC - Temp Sensor?

    Howdy all. Got a problem I hope you can help with. My '07 Tahoe LT with 260k that I've owned for 7 years has decided just working like normal is boring and has decided to throw me a curve ball. The AC (I'm in Phoenix BTW) seems to be going in and out. Like it will blow ice cold for about 2...

    Gotta Have Better Motor Mounts????

    I can't make this crap up. I am currently on my 4th set of motor mounts in 40,000 miles on my '07 Tahoe with the 5.3 FFV. First set went out just before 200k. Went to turn hard (left) into my neighborhood on a Saturday, where openings are rare, and the engine just ripped loose from the...

    Camber Adjustment??

    Howdy folks. I got me a problem. I'm hoping the experts here can help me. I am now preparing to purchase my 3rd set of tires prematurely on my 2007 Tahoe, 2WD, LT... bone stock as they get. The 1st $1200 set had to be replaced with 3/8" of tread left because the front right tire was showing...

    Rampant Electrical Gremlins - Need Harnesses?

    I figured I'd see if any of you have similar issues with the wiring harnesses and maybe solutions or sources to make them go away. I have an 07 Tahoe LT with about 230k on the clock. I replaced the engine about a year ago due to DOD issues. I figured at 200k it was easier to just do the whole...

    07 5.3 Knock Sensor Issue

    So my 07 Tahoe, with it's new engine, came up with the left bank knock sensor low voltage code. I tried to look online, but everything i'm finding is for the previous gen 5.3 with the sensors under the intake. Mine are on either side of the block by the motor mounts. Since I can't find anything...

    Strange Noise Under the Hood

    So I just finished a 4 day marathon to replace the engine, u-joints, and service the trans in my '07 tahoe. Everything worked perfectly, started on the first try, perfect temp out of the gate, perfect oil pressure, trans temp dead on, engine and trans smooth as silk, BUT... I have a noise I...

    Need wiring diagram or description for windows

    The drivers side front window stopped working abruptly yesterday on my 07 Tahoe. I need to test if it's the switch or motor, but I want to do it at the switch so i can avoid tearing open the door until it's actually time for the repair when i have parts and all that. To do that i either need a...

    Loud Engine Noise... Maybe Serious Issue?

    I have an '07 Tahoe LT 2wd with the 5.3. Bought it 2 years ago with 130k, have 194k now. Earlier this year (march or april) my wife was driving it to work daily and started complaining of a banging noise when she accelerated. I drove it and it sounded like a rough AC compressor clutch, so i had...

    Stabilitrac Gone Crazy!

    Hi all, new to the forum. Have a 2007 tahoe LT. Got some scary stuff I want some advice on. A couple weeks back the steering started getting stiff spots at slow speeds. I turned to the net because fluid and rack looked good with no pump noises. Found a bunch of horror stories about stabilitrac...
