Anyone have detailed instructions on how to remove the throttlebody on a 97 K1500 350?? Need to give her a good cleaning, does it call for a new gasket as well? Thanks!

disconnect battery, disconnect MAF sensor and intake air temp sensor, remove intake resonator wing nut, undue hose clamp on filter side of MAF, remove intake resonator by pivoting resonator upward from back,disconnect TPS conector and IAC connector and throttle and cruise cables from clam wheels on throttle shaft (pull throttle wide open and feed cable and cable end out of wheel), remove air cleaner adaptor stud ( front of Throttle body) remove the three throttle body fasters, remove assembly from intake DISCARD FLANGE SEAL. clean as you wish, install new seal when installing. if you remove the the IAC (located very front of throttle body) for cleaning be sure not to push or pull on pintle and only WIPE clean DO NOT use cleaners or sovlents on IAC. inspect o-ring for any damage, if okay re-use. Assemble in reverse order.... (:

i would rate it as pretty easy, not to many things to unplug and remove really, the worst part may be pulling the resonator peice of the top of the unit...

That was a piece of cake. Wow, not much to it at all, except the actual cleaning took quite some time. The TB was a lot cleaner than I thought, I mean for 150K, I was expecting a lot worse.

 

Anyhow, since I have the plastic pipes off, time to change the cap, rotor and wires. Hope the wires get here soon.

 

Thanks much for the write up!!!

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.

      Wiring Help, Please

      By Core-Lokt · Posted

      I'm putting in an A-pillar pod/gauges, and I'm asking if anybody can identify a (preferably) fuse for a switched power and illumination circuit on the driver's side interior fuse panel. Offhand, everything I checked with a test light was constant-hot, and I'd much rather uses a piggyback fuse. I can certainly find a wire, but I'd rather not half-tap.   Thanks in advance for any help.
