Hi Ya'll, I have noticed a bit of oil coming out of the hole in the bottom of my EGR. After a few searches i have found out this may cause limp mode, can anyone else confirm this?? And if so can it be repaired or do you just have to replace?? Also the car is revving up & down alot, like an auto choke. It also tries to run away with its self when cruising at low revs, or no revs at all. Where as a normal car would try and stall, this feels like when it gets to stalling it revs up and off it goes..
