Hey, thanks man. Those photos and captions are useful. I think this whole vaccuum system that Toyota is using is beginning to make sense to me.

 

Truck will run just fine with just the vacuum line to the fuel pressure regulator for what it's worth, the switches etc... aren't necessary. I've set up a couple this way and they all ran great. Toyota piled a lot of vacuum crap onto the 4cyl that it doesn't really need, especially if you don't have to pass emissions.

 

It does seem like there is a lot of "vaccuum stuff" going on under the hood. I'm just a backyard mechanic, and most of my experience has been working on Jeeps. Going from the 4.0L Jeep motor to this 22RE has been a learning experience! Where I live, we do not have emissions inspections or laws. I do like the "less is more" idea when it comes to things like this. I'm hoping to have some time today to mess around under the hood.....life is busy.

 

I got to spend some time under the hood after work last night. Since the truck doesn't have AC, I capped off the lines running to the white valve. In the process, I noticed that a vaccuum line running to the blue valve had been cut in two, so I repaired that. I think these things did have a positive effect on how the motor was running. The idle calmed down and seemed more normal. I think this was all good - thanks for your help.

Also, I checked for the other plug to plug in the EGR temp sensor, but did not find the other half. Doesn't sound like it's vital, though.
