Got the throttle body off. Definitely gunked. Is it enough to be detrimental? Not sure, the blade still seemed to actuate smooth. Some standing oil in the back of the intake, tough to see in pic. Need to try and dry this up i have an old catch can from my F150, but i havent got around to...

I got 2 things of SeaFoam. (1) 16oz to dump in the fuel tank, and (1) 16oz with the fancy spraying tube for direct intake fogging. I should have gotten 2 cans for the fuel due to tank size but oh well, its a start. I was going to put less fuel in but the temps are gonna be single digits the end...

Yeah, they are newer too. Will see what sticks out to me at the auto store. I like the fact they say seafoam is petroleum based.

I'm working from home tomorrow, so I will try to remove it and clean it during lunch. I need to get a gasket for it too today. I'm lost on the Italian tune up, I'm mostly scottish!

I haven't, but I am going to try to grab some after lunch today. I'm at a 1/4 tank again now so it's good timing. I always thought that stuff to be like snake oil. Contemplating on trying rhw seafoam, I have heard good stories, none that hurt anyway.

We got the Snap On scanner and scope plugged into the Yukon this AM. All "reads" normal, except for a very slight misfire at idle on Cylinder 5. It's minimal enough to not trigger a CEL, and only at idle not any bit of throttle. A cylinder balance really didnt show much deviation either, all...

Yes, just cut to your required length and re-drill 4 holes in the bottom of the rail to bolt the rails to the plastic bases. Only issue I could see is making your cuts right so the middle braces fall symmetrically. They "slip" into the bottom of the rails via quare cut outs.

That's my thought, but of course they aren't bad enough to visually tell by plug. I wanted to go look at fuel trims again, but I'm just running out of time before our trip

Cranking the miles on as a daily driver. Been noticing as I did a bunch of City driving that there is still a small bit of rough idle. Maybe a fluctuation of 100 to 200 rpm. Not throwing any codes at the moment and all monitors have been run. Going to have a shop put it on the scanner tomorrow...

Frigging salt. High has been 25 F. So no car washes yet. They have laid the salt so heavy all the roads are dust bowls. It's gonna be 40 F Tuesday but pour rain, then right back down into the teens end of this week. Roller coaster. I think I have a front passenger wheel bearing going. I get...

New wheels and tires bolted on!

Got the vent valve swapped. Swapped from the low rack: To the Z71 rack. Man this one is way beefier:

Ok, will get some on it tonight. Going to swap out the vent valve hopefully at lunch today. It's in the teens here and the Yukon is Fluid Filmed. Part of me is wondering if I over sprayed that canister and it's plugged.

First CEL code popped up today. Was initially worried that I didn't cure my issue. I have about 150 miles on it since the parts cannon. It's a P0449, issue with the vent solenoid down at the charcoal canister. In research it's most commonly the vent solenoid itself, but could also be the purge...

Luckily mine is nearly a bolt on swap! Same body style truck essentially. My current rack has 6 bolts per rail, this new one has 7 bolts per rail. I will be omitting the 7th attachment point and all should be fine. Spent time today cleaning more. A quick polish, its still pitted pretty bad...

Dis-assembled and rinsed. Lots of parts to this thing. It was nasty, spent the last bit of its time under a pine tree. Gonna throw a quick buff on the chrome tomorrow at lunch then start to re-assemble.

Ended up pulling another item at the junkyard. I've had my hopes set on a Z71 roof rack swap for a while now. I just couldnt ever get lucky with a Suburban in the JY, it was always Tahoes which are too short. Mostly just for looks although I do strap quite a bit to the roof of this thing, it...

Went to the local JY this weekend. One single flex fuel 02-07c that was in ROUGH shape. Out of 8 injectors, only 2 had plastic bodies that weren't cracked. So I grabbed them. Set up a jig to blow Brakleen through them and they both sprayed well. Swapped out my suspect injector. Ended up having...

Wow crazy. Their "stock" pictures show GM Genuine and Separate AC Delco parts and numbers. That's misleading as hell! I already tried swapping coils and plugs. Still extensive wetness to plug #6 after each run and pull for inspection. All other plugs on that bank loom good.

I appreciate that AK. We are leaving for FL the end of this month hopefully woth the Yukon for comfort and space so I am in a bit of a time crunch. I went on RA and found new GM injectors for $90 each. That's a bit wild to replace them all at this moment, but I think I am going to the junkyard...
