    Truck has always run great. Got gas at Costco yesterday and as soon as I started it and got to the first stop sign, I could tell it was misfiring on some cylinders.....you could feel the twitch at idle. Runs ok normal driving. Took a look lunch break at work with the Tech 2.....live graph...

    Cooled Seats Quit....Need Wiring Diagrams

    Anyone have the wiring diagrams for the cooled seats on a 2013 Tahoe LTZ? Probably from the battery through the door to the seats. Tech 2 didnt help much. Push cool button it lights up, blowers blow but not cool as if the power to the Peltier plate is not getting there to convert. Ordered a CD...

    Console Cup Holder Lid Bumpers / Stops

    2013 LTZ and I may have sucked up one of the little push in bumpers for the console cup-holder lid. Its where the lid rests when closed. Im not sure if it was ever there or it got sucked out at the car wash when I was vacuuming. Anyhow, dealer only sells the entire cupholder and surround...

    Scorpion 1.6 Roller Rockers Installed !

    Well I got the rockers in.....pain in the azz. The bad part of install is the entire ac compressor and power steering bracket as well as the alternator have to be loosened and moved a bit in order to get the cover over the now taller rockers. Also no instructions of any kind, like I needed...

    Strange Timing Issue After Shift....

    So here is the problem. If I take off from a light at say 20-25% throttle normal driving, after each shift the truck bogs for a second and then clears at right around 1700 rpms every time. When watching the timing live, the timing is about 20-25 degrees then shifts at say 2100 and the rpms...

    Got the Ultra-Gauge

    Well, I bought the Ultra-Gauge a few weeks ago and it came in the mail. Nice small little unit that is like the ScanGauge but has a WAY better screen and shows 6 gauges per page, 3 pages. The cool part is that besides showing and clearing codes, avg mpg, instant mpg and all the other stuff...

    Anyone Have Problems after Alternator Overdrive Pulley?

    Im not sure how long this problem has been going on, but I noticed the other day that when I get on the throttle, the AC blower motor would sound like it was blowing slower. Yesterday I did some experimenting on the freeway and figured out it is an RPM issue. Anything over 3500 rpms and the...

    Guess Which Cylinders Got the Seafoam

    I Seafoamed the beast a month ago. Put a small vac hose in the can and stuck in pretty far in the pcv hole between the MAF and towards the TB. Looks like the stock TB and its stupid throttle plate deflector made it all spray to the rear. [/IMG]

    Front Diff Pinion Seal Leak Fix?

    It is a 99 4x4 with 3.73 Has anyone repaired a front diff pinion (yoke) seal leak? It is just an oil seal, but I have never done one on a front diff. Is there a crush sleeve like on the rears or can you just remove the yoke and the seal and put the yoke back on?

    Pinout Needed 99 4 Door 4x4 ECU/PCM

    I need the pin out to the ECU/PCM so I can trouble shoot some problems including B1S1 O2 getting stuck at .449 volts and not moving, pinouts for the electric fan control from the PCM, and to try to figure out this damned fuel gauge vibrating needle thing. Any readable schematic would be great.

    Stock Alternator Isnt Gonna Cut It

    Truck is bone stock, stock radio. With 110 degrees right now, it will still be 100 at 9pm. At a stoplight with the front and rear AC on high, with headlights on, in drive stopped with your foot on the brake = 11.95 volts !! That means no Efan with the stock alternator, or 4 high mod either...

    Just Pulled the Trigger Intake Stuff

    After getting the new MFI spider, I figure why take it all apart for just that. :) Just pulled the trigger on the VMAX manifold spacer and a ported throttle body while I was at it. I plan to dyno the truck stock (K&N filter and 20's) first, then install all the stuff and dyno again without...

    A/C Temps and Pressure on a Good Running Truck

    I had to replace a leaking high side valve, so I figured I would post some pressures and temps on a good running ac in a tahoe with front and rear. It may help someone to figure out what is wrong with theirs by comparing. After putting in 44 ounces (2 lbs 12 ounces like it says) in it, I...
