hello i need serious help...my car like bogs around 2k rpms..it seems like the car is holding pressure or something and when its like that if you drive it then it bogs around 2k but once its bogging if u stop on the side of the road and u let it idle and then it seems like its surging for air or something, then when its surging after a while it releases pressure then when that is done, and u drive it then it seems like the car runs fine?? does anyone have any clue why it does this?????
