Explorer Intake vacuum lines... Car idling badly... Help August 15, 2015, 04:03:44 PM I just need some help on what I can cap off and what I absolutely need to run so that the car will idle better. If I put my finger over the larger hole, the car shuts off. So I know I need to run it. Thank you! Quote Selected

Explorer Intake vacuum lines... Car idling badly... Help Reply #5 – August 16, 2015, 07:05:44 PM Stock configuration vacuum lines.....If you're having an issue where the car shuts off by capping a vacuum source that has been deleted and have not removed the MAP sensor from the equation, you need to reset the base idle. Leaving that port open to the atmosphere is introducing a rather large vacuum leak.....Since you are still running Speed Density, it is necessary to run the line to the MAP sensor. Quote Selected

A B303 cam/SD/vacuum leak will though. Quote Selected
