my ssei has been running poor and rough idel, the intake gaskets were out so i put those in, still idels rough, i have code po122 for low voltage to tps and code po107 which is for the map sensor. I dont think i have the map sensor hooked up, i have a white 3 prong connector i can figure out where it goes.

Very common for the connector tab to break off, letting the connector disconnect. When you put it back on you might put a ziptie around it to hold it.

Thanks for the pictures. I got the map sensor hooked up, there is a vacuum hose connector on the top of the iacv on the front right side of the engine. I had that hose connected to the one that suppose to hook to the map sensor. Do you know where that hose needs to go or have a picture?

There should be two major vacuum lines.

The red one goes from the BCS (Boost Control Solenoid) to the FPR (Fuel Pressure Regulator) to the LIM (Lower Intake Manifold) under the supercharger snout, and then finally to the bottom of the MAP (Manifold Absolute Pressure).

The yellow one goes from the EVAP solenoid to the TB (Throttle Body)

Also, you should leave this port unplugged, like this. (I didn't see that huge vacuum line you had running across the engine before)

The last picture, the port i was wondering about is above the big hose on the boost control solenoid. I hooked a hose up to it( the one running across the engine) and plugged the end. I will just take that off and leave the port open. I put in a new tps and that code went away and rps seamed to return back to idle, hooked up the map sensor and that took care of that code. still idles rough, going to put in new o2 sensors and see what that dose.

That clip holds a small foam filter, but no hose is attached.
