Ford Ranger 3.0 HORRIBLE Fuel Economy and NO POWER *FIX*

My ranger was getting 13.5 MPG (17L/100kms) and very slow acceleration until I DID THIS!
Hope this helps many ranger owners.
Please share this video with a friend that has a ranger or Mazda b3000 as most people with rangers just accept bad fuel economy as I found out reading through forums. There is NO REASON a v6 small truck should get 13 miles per gallon.
