I picked up this Ford Ranger to do estimates and other small running around so I wasn't always driving my big trucks. The Problem is that it gets the exact same MPG as my 3/4 with a fully loaded trailer. Its a 4 cyl. with 8 spark plugs. I changed the air filter and I cut the muffler off and straight piped it. I left the Cat converter still in place and I'm thinking I should have cut that out as well. Its totally gutless and it only pulls off 15 MPG. I like to resell the truck but it takes 8 weeks to get the title bad from processing from me buying it. I'm pissed.
