Confirmed 3 bolt housing today on my daily fluid inspection. We are leaving FL early Saturday. Supposedly back home is getting hit with "feet" of snow today though tomorrow. Fingers crossed it's clear for our return Saturday evening. May have to pull in the drive and hook the plow up before...

This is the main reason I want a new cast unit and not reman. Still need to see if my unit is the 3 or 4 bolt cover.

Well, I totally forgot to update this but we made it 1,100 miles to FL in the Yukon. The throttle body cleaning and power supply (disconnect neg. Terminal) removal didn't solve the idle issue. Just for the heck of it I then replaced the No. 5 cylinder coil pack with one I got from the junkyard...

Only port in the throttle seems to be PCV valve and fuel tank purge line. Really the most simple one I've messed with! My understanding the IAT on the 5.3l is in the MAF housing. I actually cleaned the MAF with proper cleaner at couple weeks back, it was super easy to do at the time. You are...

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.
