I have japnese lancer 2006 evo having 2l enginge 4g94, i am facing problem in adjusting the high rpm, we changed the rpm sensor, cleaned crank and cam senor, reset the ecu, drive 4 days around 300 km but the rpm is still high on parking mode its around 1100, on reverse 900, neutral 1000, drive 900, please suggest how to settle this on standard rpm
