Throttlebody Problem, Different Stock Intakes?? Options

Two Different Intakes, Throttlebodies...

One for Convertibles, one for Coupes and Liftbacks.

So I put another 5sfe engine in my car and it's running like ****. Garage said there was no vacuum to the Fuel Pressure Regulator, even though the vacuum line was connected from the intake.
So, I thought, pinched line, or clogged tube.
OR
This...
As you can see in the links, there are two different throttle body's listed for the 5sfe motor. One has a third vacuum pipe coming off the top facing the driver's side, and one has the third pipe facing the passenger's side. My original car had the one witgh all three facing the same direction. The new motor I got had the other one. So I swapped back to my old throttle body to keep it consistent with the MAP sensor placement, and other parts on the car. HOWEVER, I did not switch the intake as well.

My question is, does anyone know if these throttle bodies will only work with their respective intakes? Or are they swappable?
This could be my issue, if the gasket is covering a vacuum hole, or if the old throttle body just doesn't line up with the old intake...That could be restricting the vacuum flow to the FPR hose...
I never had the car running with the other throttle body to tell...

iirc the difference is for engines with EGR and engines without EGR.

That doesn't really answer my question...

[Bitter]

you can't compare the 2 throttle bodies and then call the local toyota parts department to ask them if there are 2 different gaskets?

[joeladam02]

The other throttle body and intake are 350 miles away now, so no. I can't...

[Bitter]

you can still the the gasket thing.

[joeladam02]

I can check the gasket yes, but there's really no way for me to tell whether or not it's right without knowing if the throttle bodies are proprietary to the intakes...

[Bitter]

call a dealer and ask the parts department if the throttle body, gasket, and intake manifold cross over for all years/bodies or if theres a difference between years/bodies.

then use the VIN on the 'new' engine to order the right parts.

ahhh good idea...that's probably why the dealer asked me for my VIN today. They told me they list somewhere around 20 different throttle bodies for 5sfe motors. I've seen two...
But it's a moot point because I drove 350 miles and got the original throttle body back today and it didn't solve the problem. Cylinder 4 misfire and Idle-Up Valve not functioning properly when I turn on the A/C.
Maybe the intake is plugged up, or the Fuel Pressure Regulator is fubar'ed. I've spent $500 at the garage and it's still not diagnosed. Shoot me!
