ill start out by saying ive got a 97 ranger with a 2000 taurus 3.0L in it. i have replaced everything in the fuel system (injectors, fuel rail, fuel pump and everything in between) i also have replaced everything in the ignition side of it too. and the code is still there. im not sure on where to go from here. and help would be greatly appreciated.
 
also don't run your plug wires too close together, be sure to criss-cross them.

do you have any vacuum leaks? new injectors, or used?
 
yes all the plug wires are on right.
i can not find any vaccum leaks and the injectors have about 5000 miles on them so they are pretty much new
 
do you feel a miss? or is it just setting a code?

the funniest things can cause this code. an o2 sensor or a crank sensor with excessive noise.
