Ford Explorer 4 0L SOHC Rough Idle Part 2 Vacuum Leak Hunting

In this video series, I will show you how I am attempting to fix a rough idle on my 1999 Ford Explorer 4.0L SOHC. I will show you how I used my inexpensive obd2 scan tool (with live data) to troubleshoot my vehicle. I used the fuel trims (long term) to help diagnosis a vacuum leak. Then I will show you how I found the vacuum leak. I tried several methods to find it, and I demonstrate a few of those methods. In this end I found the vacuum leak with a homemade smoke machine that I converted from a fog machine.
