New here...but have an annoying issue with my '97 5.0. After the first start, the idle speed stays at 1500-2000 for about 15 seconds and the car begins sputtering and dying out. My OBD II reader pulls a P0171 code, so I do not think that the MAF or IAC are at fault (no P0174 code means that it is only one bank, more than likely). Interestingly, it does not start dying out at traffic lights and other times at idle...just after a startup. The car will behave like this whether it is the first start or the millionth start of the day; it does not matter whether the motor is cold or hot but that it has just been started. What does this sound like to you? I just poured a bottle of Techron into the fuel system to begin with something easy. Thanks in advance! Lovin' the forum so far!
