Question about 2003 Ford Taurus
Do you have access to a scan tool? A more common cause for this condition is a vacuum leak. You can verify this if you check your long and short fuel trims. If the numbers are above 10 percent at idle and drop when you raise the rpm, you need to check for a vacuum leak.If they stay the same then I would look into the fuel pressure and volume.Hope this helps. If not, hit me back and I'll see what else we can do.Good luck.
