Default 2006 Verona P2070 and P2138 codes

Hoping to get some help here. I was driving my Verona on the highway home last night and it was pulling like normal, but about 30 miles into my trip, I found myself pushing the pedal further to the floor to maintain speed. I soon found that I had to floor it to just go 60mph, and it had a complete lack of power. So I exited the highway and pulled into an O'reilly's, to check the engine codes.

Mind you, the check engine light is currently already on because I need to replace the thermostat, just waiting for my income tax return since it is stuck open, so I am assuming these codes both came on simultaneously, since I have had no acceleration or power issues until just now. So the codes are for:

P2070 Intake Manifold Tuning Valve Stuck Open
P2138 Accelerator Pedal Sensor 1-2 Correlation

So I was poking around the engine to see if a vacuum line was broken, and had this break while I was checking:



It is on this item here, the line on the bottom right of the thing I am holding:



Can anyone tell me what this is, so I can replace it? And is the Intake Manifold Tuning Valve the part in the top center of the pic, straight up from the part I am holding?

Well, for an update, I never got this problem truly fixed, but it was Verona fixed. There is no concrete evidence for this, but I think that dirty oil was the culprit for the codes. I know some older imports have issues with dirty oil causing various sensors to either go bad or report faulty information to the cpu, so I think that simply running some seafoam through the oil at least once a year along with proper oil maintenance will keep others from this issue.

For complete disclosure, I have various and intermittent sensor issues with my Verona, and I was suspecting an alternator problem, but it checked fine and checked by 2 different tests. I WILL NOT pay hundreds of dollars to have a dealership do it, and I don't trust one to use the actual equipment for this car, for obvious reasons.
