So my uncle and I just did a complete engine swap. His old engine was shot. After getting done we started it up and the idle is really high in park. The car drives fine. It is only high idle in park. So I it did throw a code p0507. Not to sure what to do. Some people said I need to do a computer brain reset. Any help would be greatly appreciated.

See picture for causes, but first check for a vacuum hose or PCV hose off/disconnected including power brake hose if vacuum assist. Then clean throttle plate and IAC hole with choke cleaner on both sides of plate. Finally drive above forty mph for a mile or so then recheck.
