high idle rpm, 900
my track car's Idle rpm is high, usually almost 900.
It used to hold 780~800, but recently 900. Usually it shows same pattern, engine start -> 900 or engine start -> 650 -> 780 -> 900 There is no rpm fluctuating. After driving, rpm is 890~900. 900 at cold start. always 890~900. hmmmm <my mods and parts related to engine> lithium battery new alternator new spark plugs & injectors new throttle actuators new O2 sensor x 4ea new fuel pumps all air conditioning parts removal Akra evo / secondary air pump removal / under derive pulley ECU software is stock with SAP, 1st CAT and speed limit removal. plz advice me~

Could be engine adaptations need to readapt since you put in some fresh parts in your air and fuel system.
