I have done the upper intake but I still have a cold-start miss that goes away very shortly, What I have done----

upper plenum "o" rings
brake booster line, did NOT replace "o" rings on plenum
tuning tube "o" rings
plugs
checked MAF(cleaned)
upper radiator hose w/ thermostat complete (Not related to miss)

If I check codes get P0176 (lean bank 2) can reset but comes back on next cold start up cycle below 70* ambient,

I need lower 'o"rings I'm sure, MY question is on replacing them what else do I need for the job, if someone could list I would be thankful.

EG.other gaskets, parts, I will get them on order.Also Do's don'ts if there are any that are important.I thank yous in advance for any advice

As for doing the lower o-rings, if you can do the uppers, then the lowers is just 6 more bolts as I recall. No special tools are needed. The only thing I would possibly say is to have a box of fuel injector O-rings standing by. But, this is only needed if you remove the fuel injectors from the fuel rail. You can leave the fuel rail attached to the lower intake and then move that lower piece as one unit. Makes getting at things a little more difficult, but can save from having to dismantle as much stuff. But then, removing the fuel injectors and putting them back on is pretty easy. The issue comes when you are trying to remove the fuel rail from the injectors, the o-rings like to roll and they will pop off with the fuel rail and have a tendency to fall into a hole that you can not reach with your fingers. Having a set of mechanical fingers handy is a life saver too.

Wish you lived closer to me. I would tell you to come by. We could get you done in about 90 minutes.
