All, I just got a '98 Ranger 4.0L, which came complete with a set of P0171 and P0174 error codes. The PO has previously swapped 2 O2 sensors, I was thinking about trying to find which ones and swap the other 2. Before I did, I wanted to check on some of the cheaper and more likely culprits -...

I have a '95 B3000 and have been having trouble with the cabin HVAC vacuum. I have a parallel thread over here about that, been trying to chase down why doors aren't opening and such. But I believe I have a much more major vacuum line hookup problem, courtesy of the PO. I have been trying to...

All, First time poster, second guessing my choice to buy a used '95 B3000 that needs to make a trip x-country next week. I'll start by saying that I've been reading as much as I can on this topic, enough to be dangerous, but not enough to know what I'm actually talking about. Here's the...
