So I have a friend who took the EGR valve off of his ka24de. The timing is set right but the car is in limp mode. First thought was maf but could it be possible that after remvoing the egr that it is putting the car into limp mode? Thanks
when i removed mine the car never went in limp mode. More info on its drivability issues please. To help us aid in solving your issue. 
Fixed the problem, thanks
