What did you do to your NBS GMT800 Tahoe/Yukon Today?

[03catburban]

May I suggest adding your build thread to your signature?

Done and did

Started tearing this thing out finally. And i didn't even round out the torque converter bolts, lol.
Hoping to get it out tomorrow and get HP tuners ordered. Still have a few more things to buy, but I'm getting closer for sure

What are your plans?

Hi all, Nic here from southern IN, swapped the cat eye and did 6" of lift with 22x10 Centerlines with 35x12.5s, headlights, tail lights on my 05 Tahoe LT this last weekend. Certified mechanic. Hope to be as helpful as I can around here! Cheers!

Welcome from Western MA!

Unlike other car/truck/SUV owner groups I have been with, people with bad attitudes and negativity don't seem to be here.

You'll find out quickly, the folks on this forum are helpful, respectful and friendly!
I am sure you'll fit right in...

What are your plans?

I got fancy wire loom and tesa tape, so im gonna get the bay cleaned up a little after I get this yanked out. Probably put a pitman and idler arm in while they are easy to get to. I still need to paint a couple things like the coil brackets and steam tube. But it's been cold and if I paint in the garage it seeps in and burns off on this furnace and stinks the whole house up. I got a thing to pulse the injectors so I can clean them, and new o-rings and little basket filters, but I'm not sure my injectors even have filters.
Was thinking about LS Droid/TunerPro for tuning, but I think it's probably gonna be worth it to just drop out for HP tuners, because there are a lot of videos for cam tuning, and it seems like most people just use LS Droid to remove VATS and stuff.

I also need to pin the electric fan to the ECU, and buy a wideband probably.
I should have just bought a crate engine, but building my own definitely gave me some more knowledge, which can't be that bad, lol. I probably should have bought a stock cam, or another engine with an unchewed cam, lol.
I am dub had to tell me about scope creep, and it's definitely real...

Took a day off of work and had lunch with a couple of friends, then drove her to two UPulls to see what I could find. Picked up a couple of Esky appliques that I will need to paint; each has a blemish on the outer edge. Trying to decide whether to color match or do them in (matte?) black.

so noticed my temp and compass went out on the rear view mirror a few weeks ago. do a google search and it looks like i need to get my soldering iron game on. good thing it looks super simple. last time i had to re solder a Climate control them resistors were tiny.....but i got em fixed first time round. so a win.

I need to fix mine as well. Sometimes the display works fine, then sometimes it's VERY dim, so dim that I can't even read it. You have a link to a good write up on repairing these? I've honestly never even tried, but I'm sure I could do it cuz I'm pretty good at soldering electronics and stuff.

Color match for sure.

I vote color match.

For your referenc, Here is matte black on my old redfire metallic Tahoe. Never got around to color matching them.

mine just went out. no sign of life since dec. im guessing ive got a large crack like the one in the vid.

New power steering pump and hoses since the front shaft seal was leaking on mine. I used ACD 15909826, listed for 2006 1500HD trucks with 6.0. Apparently this pump better to help with the 20s wheel those trucks came with. Also a new coil for a P302 code. Steering feels great!!!

I didn't need to know about another upgrade, lol

Neither did I until I searched upgrade power steering pump for our chassis and ran into a video. It discussed the 2006 silverado 1500hd max trucks with the 6.0 and the larger wheels. DELCO lists a different pump for those trucks. Something about and B4V RPO code. Helped compensate for the factory 20s that year model came with. So I bought it and had it installed this morning. Steering feels great!! CEL is still on after the new coil for a code P0302

 

[blueinkd]

CEL came on Saturday. Truck had new ACD 41-110s gaped at .040, new tsp wires less than 90 days ago. Probably 6-7k miles now. I bought a new ACD coil day before and seemed ok but CEL came back on. Tonight I pulled the plug and installed a new 41-110 @ same gap.

Any thoughts on old plug?? Looks fine to me based on my research online. Only code present is a P0302

Nice! Great info & upgrade!

plug looks good to me. What was happening with the coil? It seems pretty rare the coils have problems on these trucks. You had already replaced one? What led up to that?

This might need to move to Engine topic, so others will find it and maybe get some help from what is discovered.

That said, how do the wires and connectors leading to the coil look?

If all are good, then there is a chance the misfire could be related to an injector or the wires/connectors to that...

I was getting single cylinder misfires on my 4.0L Jeep. Right before my fuel pump died. I believe the fuel pump was weak and not sending fuel to the end of the fuel rail with enough volume/pressure.
On the 4.0, the misfires were P0301. Number 1, which was all the way at the end of the fuel rail. That happened a short while, then my fuel pump died completely. After the new pump, I never had an issue with misfires again.

Just wondering out loud here on a long shot theory... Your code is P0302. Number 2. All the way at the front. Is that the end of the fuel line? Is it possible the pump is not send enough fuel up that far like mine?

May be worth doing a fuel pressure check to see what kind of pressure you get on that rail.
Who knows, maybe you have pressure for days. But wouldn't hurt to rule out possible issue with the pump.

Thanks for the advise. Going to get my buddy to put his diag scanner on it and test fuel pressure this weekend. Fuel pump probably original one and gauge reads erratic going on 2 years now. May be a win win here but we will see.

Worth a shot! Cheap and easy enough to check on. I was just surprised at what my Jeep was doing. Had the pump not died, I might have been chasing electrical tails forever or continuing to ignore until something surfaced as the cause for the misfire.

Good luck! Keep us posted. Even if this theory does not pan out... Can still be helpful to others.
