Question about Ford Explorer
I have replaced the plugs and wires,and fuel filter and it runs ruff yet it comes up with no codes showing probums email@example.com
The computer is the only thing that will not throw a code since it cannot tell on itself, but have you checked to see if there is water in the fuel? Seafoam is a good product to use to try and displace any water in the fuel. I am not saying to do this, but... on my offroad car (not for street legal use*) I pour one bottle of the 90% isopropyl alcohol in the tank with as low of a tank of gas as possible, and it usually does the trick. Water in the fuel will do pretty much exactly as you are describing, so it might be worth it to try one of those suggestions, hopefully someone with one of these trucks will be able to shine some light on the subject, good luck

New plugs and wires?
Double check to make sure that you've got the routing and firing order right... if you have 2 switched, the car may still idle well but then pop and sputter on harder acceleration.
The next step would be to run some "Complete Fuel System Cleaner"... If that's the problem, you should see results within 20 miles or so.

sounds like EGR valve and sensor this controls idle speed when at a stop. the po171 is a burn lean or rich code need to know what bank 1 or 2. also check for a vacuum leak from one of the hoses.
