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

[Doubeleive]

It initially gave me a p069e but that went away, now I am testing all the modules has some ebcm codes, rear seat heater core, etc I am going to clear them all and test again, something isn't communicating

Now after messing with it I have some stupid u0073 code and the tech2 wants to go full retard

 

[89Suburban]

what brand did you use?

TRQ from 1A Auto. I disconnected the battery and grounded the positive to the frame for a while and I had a single P0300 code I cleared out with my pocket scanner and all seems better so far all around. Fingers crossed.

I'm getting a persistent U0073 which is a low speed canbus A, code the tech2 wont really run and tech2 win keeps telling me i'm getting low speed, no clue where to check the canbus at

poked around a little bit and found the 2 main connectors under the fuse box were dangling when they should be attached to the splash shield, this has caused the wires under the fuse block to be yanked on (sort of) wiggled them around a little bit and put one clip back in the hole where it should be the other one the clip is broke. code is gone now & the tech2 is communicating properly so.... I don't know if that was it or not but I guess I need to find some clips or just replace the fuse block or whatever those connectors go to. The fuse block gave me a problem before when I had some bodywork done and it wouldn't start till I banged on it a few times.

Fun times....stupid door molding falling off so redoing it. Found 2 nice spots were the paint had came off under one of the corners and now surface rust. Cleaned up and touched up before i put the molding back on

Think that street sign had something to do with it or the 109 mph pulls?

Kimd of like when Jimmie Johnson was promoting Extendz

Car Shield is the one Ice-T is selling on TV. I figured it was a sham. Anytime they resort to celebrity endorsements it usually means rip off.

Replaced the rear liftgate window switch in about a minute thanks to a video a member on here made some time back. Bought a fuel rail adapter and an ethanol test kit (little beaker style bottle) to check the actual alcohol content of my fuel. Last time at the station, the content dropped 20% into the 40s and it should have at least been in the 70s. Either we're getting cheated or the computer got a math problem wrong.

Deets on the fuel rail adapter? Do you have to remove the valve core? When I tested mine, I removed the core and slipped a length of EFI hose over the port. Had the hose routed into a clean bottle and turned the key on for about half a second. I'd like to not have to remove the core- don't wanna wear it out and have a fuel leak.

I was out and about today in the yukon and as I was walking up to to it from across the parking lot I noticed the left side looked lower than the right and sure enough measuring at the wheels both front and rear is 1/2" lower on the left, wth? I measured the front first and thought maybe a bad strut or something could be the problem but it's on the rear also
any ideas? how would I correct it? I have the z55 and everything is working fine. tire pressure is within .2/10'th. gas is at about 2/3rd's

As the other's said, it's the "Chevy Lean" or "GM Lean". It's not so noticeable until you lower a vehicle. When I lowered mine, I left a spacer ring in the left side strut drop it 1/2" less than the right side to level it left-to-right. It'll vary 1/8" or so after driving and when parking on even slightly sloped surfaces.

Who manufactures the O2 sensors for ACDelco?

With 136k on the clock, thinking it might be time to replace as PM. Amazon has the ACDs for approx $47 each. Denso is approx 30-37 each.

No, it depresses the schrader valve as you screw it on. There was enough fuel under pressure to fill it up the bottle if it hadn't all leaked out as the hose was too big, needed 5/32 but only had 3/8" and big tie straps. Not enough to squeeze it down. Anyway, will try again later after a trip to Home Depot.

If there's not enough fuel and or pressure, we'll use the Tech-2 to turn the fuel pump on and off until the beaker is full.

FYI: This is two pieces, the barbed end with the schrader valve depressor slips into the knurled and threaded fitting.
