I know Google says 29d0 is cylinder 4 misfire, but his screen shot says electrical short on his intake air sensor. Check out the attached list of n55 codes I have, it aligns with OP's screenshot (just use search function for 29d0). Here are some screenshots of what it says to check for regarding this code.
I believe this points to the tmap or tmap wiring? (tmap = temperature & manifold absolute pressure)
