sup. for the past few weeks, my EVO is not working correctly.
when ever the car is in idle or not in gear, my rpm will stay up around 3k - 2k rpm,
riping up and down. but when the car is in gear, the car seems fine.
anyone has any idea what's wrong w/ the car? do you think it is the throttle body? i had to reset my battery and the car seems fine again but in a few days, the problem comes back? what can i do to fix this problem.

 

do you have a CEL?

 

what mods have you done to your car lately????

 

Vaccum leak. Hose popped off.
