What is the exact location of the orifice tube on my car it has the 3.1 V6? A diagram would be very helpful.

Yes, it does have one and it is buried pretty good. It is in the liquid line that runs along the left inner fender well, under the brake booster. If you look closely at the line, you will see a connection and dimples in the line where the tube is located.

Check out the diagrams (Below). Please let us know what happens.

Cheers

Thank you so much Wrenchtech! That is way easier to get to than at the evaporator where I thought it might have been. Which would you recommend, Mitchell or Alldata for a service manual?

I say Alldata for sure. Mitchell has some advantages mostly in easier to read wiring diagrams, but Alldata has them beat in every other way.
