In my quest to appease the fuel vapor nazis.. er, the eh CEL P0455.. I replaced the vapor purge valve solenoid today. AC Delco part of course. Man, this intake is embarrassingly dirty. I think I need a need a TBSS, or NNBS intake to replace it.. [emoji3166]... but in the meantime, hoping this settles the CEL down and I don’t have to go further with the more fun parts replacements.

If this is just a solenoid/valve couldn’t you have done a quick check by applying voltage from a power source?

I was kind of wondering if the Tech 2 menus for our years would have an emissions test to pull vacuum on the whole system to see if it does it and holds. I've had the occasional "tighten gas cap" message, too. I'll have to give it a try with my Tech 2 next time I drive it and think of it.

As long as it wasn’t full of charcoal pellets to the purge you’re probably good

Hate to tell you but those other intakes are ugly too. You need one of these. They really dress up the engine bay.:cool:

What made you install it? Having issues with the frontend?

Just cause all the positive rave about it. Cheap enough to buy plus I'm sure the bigger wheels on the truck adds stress to gear box. The way I see it, it will only prolong the life of all the new chassis I just installed.

Just now installed the kyb steering stabilizer. What a pain in the butt!! Bout to clean up and take it on a test drive. View attachment 276774 View attachment 276775
I didn’t find mine hard to install at all. Only had to drill one hole and the rest amounted to about 4 bolts. But then again anything done while laying under the truck and working over your head sucks.

Some over on the suspension sub forum also installed it and gave it great feedback. Probably will be ordering the energy suspension sway bar bracket/bushings he installed for the front and rear of the truck.

The current hole there needs to be opened up to fit the big bolt included and drilling the extra hole for the 5/16 bolt as well. You are right, it wasn't bad just the instructions aren't worth the paper they are printed on. Also I was missing a nut in the packaging and had to resort to finding one in my tool box.

Now that I know how it's done. Next one going on in less than 15 mins. I just didn't want to booger anything up and make my truck faster by drilling to many holes in and and reducing weight.

Looks good man. Why couldn’t you wait..? Brakes making too much noise..? [emoji1787] I pushed mine out a week for the rears.. need brakes in the rear and they’re driving me nuts, but after first thinking I’d just go with standard brakes, changed my mind.. so getting the Z36 kit for the rears as well. Install is this Thursday. Of course, when I painted the front GMT900 calipers, they look ok, but are a little dinged up already. So I then decided I’ll also get the powder coated rear calipers. Lol. Those aren’t here until next week, so will be a separate install, but oh well. Today, I’m touching up the front calipers with some brush-on POR-15.

After 2 coats.. that’ll do.. if (when) they need another coat, I’ll probably just get the powder coated front calipers as well. This way I’ll get to see how the rears hold up though. [emoji16][emoji106]

Are those the ones I sold you Sam or did you end up buying new ones?
