So i recently had a coolant leak from one of the turbo inlet lines, so i removed the turbo fixed it and put i back. Problem is now it wont idle. I fire it up and its ok for a few seconds then it drops to around 2k revs then drops to 0 and dies. If i give it throttle its ok and sits comfortably around 3k no issue. I have been over all vacuum lines and made sure they are all ok.

Thanks
