My ford contour has high idle speed and makes a lot of noise. When I change the gear, the car moves and make noise heavily. While driving also, I do not need to press the accelerator, the speed increases (due to high rpm). I just control with the brakes. Speed generally goes upto 40 mph or perhaps more. Please help me with this. I really dont have any clue what to do. I even showed this to a local mechanic, but even he is clueless. However, we figured out 3 error codes by plugging in the computer, error codes OBD2 are P1506, P0102, P0122. I even searched for these error codes, but really dont understand what do I need to do. Hope to hear an answer. Please help me!

I looked into the codes which are in the order you posted

p1506 idle air control over speed error
p0122 throttle positioning sensor low input
p0102 mass air flow sensor low input

sounds like it could be a vacuum leak look for disconnected or broken vacuum lines or have your mechanic check for leaks l

I tried to find the leak as you have mentioned but could not find any. Even mechanic told the same, but he said there were no leaks. Then he disconnected a jack, and he said that it would drive the car in default condition, the sound got better while driving after that, but when we stop the car, it shakes and engine seems to move as well. So what could be done. Btw thank you for the response. I really appreciate it.
