I don't guess I've heard of them having a "Pinto" engine before. I'll admit that I would likely not be happy with a 4 cylinder Ranger, and I don't know for sure about engine options in other years, but in 2001 they had a 4 cylinder and a 3.0L V-6, as well as the 4.0L V-6 that I have. Horrid fuel mileage?? I keep much more detailed records than most, but I bought my 2001 Ranger on 12/20/2004 when it already had 36,086 miles on it. But since then it has averaged 18.387 mpg, nearly all "city" driving and I DO use the air-conditioner. The EPA ratings did change from what they were originally. So I'd say I don't get GREAT mileage, but under the circumstances, I have no complaints.
