Ok. I think I might know what your problem is. Under the throttle body theres this little valve thingy thats bolted up under there (3 10mm bolts i think) a little coolant hose that runs around that area of the engine is connected to it. Unbolt the valve module thingy and you should see a circular-ish panel screw onto it (2 screws). Unscrew that then you should see this white thing inside of it with notches on the top. Use a lflat head screwdriver and screw it all the way down, screw and bolt everything back up and run your car. You should be fine after that. Let me know what comes up.

No, you don't have to replace that. That just screw in that white plastic valve. It acts like a screw.
