I have a 2002 Taurus that has developed a miss. It's a 3.8 Duratec with
70,000 miles. At idle you can feel the miss very slightly (about 1 miss every 10-30 seconds, not steady), but when you turn the AC on you can feel the miss allot more. Also going up a hill at low RPM's, very sluggish. But the strange part is that it does not do it all the time. I have not been able to determine exactly when it does it and when it doesn't. Very frustrating....
