Rough idle at normal or cold temperatures either in gear or out and also if air conditioner is on or off. This is occuring on a 2003 Ford Ranger v6 3. 0l . . Ford dealership gave me a copy of a service message under 618400 rolling idle special service messages 16180. . It states if the condition is still present, make sure your wds is updated with the lastest calibratuon files, wds release b20. 10 or later and reprogram the pcm. They did that and I am still having the problem. I have been doing some reseach and it seems they have had this problem since nov02. According to the mechanic I talked to stated if it didnt fix the problem dont worry Ford is trying to correct the problem. It has been 8 months now. Do we know if they are actually going to fix the problem?.
