The valve you pointed to in the video is for checking the fuel pressure. It's on top of the fuel line going into the manifold. I've done the fuel pressure check using that particular valve many times.

 

Thank you so much! Now I don't have to look that up.

 

Well...in the video, I turn on the A/C to check the idle with a load. I stuck my hand out to check that it was blowing cold. It was.

Now that my problems are resolved, my A/C actuator isn't working! All the air blows out down low and from the windshield. No vents. I MUST have knocked a line loose under the hood.

GRRRR!!!

 

Check your 4x4 also, see if it works.

 

Found the vac line that pulled off...it was beside the distributor cap. A/C changes properly now.

And as a side note:
Pre tune-up mpg = 13.2
Post tune up mpg with A/C running constantly = 16.0

 

Just a new MPG update:
The previous tank gave me 17.7 MPG!
Today's fillup revealed a whopping 18.3!!!

 

That's more like it. I usually average 18-19mpg. My best ever was 19.3 on a run down to Portland and back.
