Today I removed my TB, cleaned it while it was off, removed my intake manifold as well tk access alternator power wire doing a big 3 wiring upgrade, changed gaskets, put everything back properly, now my car is idle hunting in neutral mainly, tried disconnecting battery for 30+ minutes, cleaned MAF, reconnected, and went for a drive for 30-45 minutes, rpms are normal while driving on hey, but when I get into neutral the idle is still jumping from about 1200-2600 give or take, not sure what else to do, if anyone has any advice I’d appreciate it. Car 2012 Si coupe. TIA
