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....

I tried the mist test which showed nothing. I then replaced the spark plug
wires and it took care of the miss, for about a month. Now the miss is
back????? It is REALLY noticeable when the air conditioning is on. HELP
!!!

Is the check engine light on? If so, did you have the codes checked? This
should tell you which cylinder is missing.

Did you replace the plugs? How many miles on the engine? Any moddifications?
