01' Taurus Sputtering and Rough Idle
I have an 01' SES Taurus just the 12 valve 3.0L V6. It has sat for about 6 months, with me occasionally starting it, until this past August when I decided to get it registered. I have recently changed the steering pump, EGR valve sensor and tubes, and had the oil changed when shortly after, about a week, it began to sputter and give lose power/ability to accelerate. The car runs fine for the first 10-15 minutes then it slowly begins to give me issues. The problem progressively gets worse until the car will eventually die. The check engine light came on and I got the codes po174 and po171. Unfortunately I sought the assistance of Auto Zones employees and replaced my MAF sensor and o2 sensors to no avail. Any hints as to what to check? I appreciate your time and assistance.
