I have had a new Nissan long block installed recently and it has a air leak because it idles @ 1600 rpm.All the vacuum lines have been zip-tied so it narrows down my search for the vacuum leak.This is on my list of things to fix but my first concern is when the car idles @ 1100 rpm and under load driving,you can feel the engine hesitate or shudder on each cylinder about every second.Is this fuel or timng related?
