i cant check my codes until i go to my tuner on thurs bc my setup doesnt have a jumper, anyway yesterday i cleaned out the iacv and the car ran great all day, until last night i downshift and the motor starts to buck, cel comes on and now the rpms stay at 2k... thoughts? all connections are good, all maintanence is good, its a freshly built/tuned ls/vtec.

 

 

im going to my tuner so he can check for codes on thursday, until then, does anyone have any idea why i am idling at 2k+ with a cel? so i dont have to drive it.
