2004 Ford Taurus 6 cyl Two Wheel Drive Automatic 175K miles
I have a 2003 Taurus.
I have been battling various emissions issues for the past two months. SO far the tally is FOUR oxygen sensors and several chewed vacuum lines (courtesy of warmth seeking rodents).
The dreaded "Check Engine" light still remains and the codes reported are P0401 & P0174.
According to my maintenance manual those are respectively 'EGR Insufficient Flow Detected' AND 'System Adaptive Fuel too lean (Bank 2)'.
Another symptom is that the car seems to run fine at high speed i.E. The highway but when idling it idles roughly and sometimes will stall.
According to my maintenance manual the EGR system shouldn't really be a factor at idling time.
Can anyone point me in a direction that could lead to my solving this issue without hemorrhaging more cash?
Otter River, MA
