2002 Honda Accord Idles rough in park only

Hello, fuel injected vehicle doesn't have such wild swings of idle speed from cold engine to warm ("Choke" - not applicable here....). Any time you have high RPM from the engine, it sounds like a possible air intake leak issue, allowing unmetered air into the intake manifold, causing high idle. Check for vacuum or air intake leaks.
