      Either the plugs and wires fixed it, or the fuel filter. My guess would be the fuel filter. Thanks for the support.

      I ended up trading off the Explorer. I had a mechanic check it out and he found a busted shock, front bearing going out, and bad ball joints (i think if memory serves). Also, I put thicker gear oil in hoping to silence the whining, but it didn't work. The axle seals wear also leaking. So to fix all those problems and replace the rear end was going to cost 1k. With the motor having 213k on it, I thought it best to let it go.

      My suggestion to others. Have a mechanic look over a vehicle before you buy it. Had I spent $30 up front I could have saved myself hundreds.

      I have had the same problem as well. I bought the part, Motorcraft #KCV 190 . I am not having any luck trying to locate this PCV elbow tube anywhere. Know if its between the intake and firewall then I definitely will not be able to get to it.
