Another noob question from me. My evo8 will be idling fine and driving fine then as soon as i wide open throttle... Right after when i go back to idle the idle is bouncing around? You know like a civic lol
Help is greatly appreciated

 

any background info on evo? mods list?... was it after install of a part?

how high does the rpm bounce around?....

you saying like if u open her up... you put it in nuetral while car is moving and the rpms start bouncing around?
