Hello all again. I have a 2000 Taurus with the standard engine. Strata it to go to work this morn and it started with a slight rough idle which is nothing new revere engine a few times no higher then 2000 done and went away. But the problem is I moved less then 100 feet and Ann hearing a dragging sound almost like a dragging exhaust. Get out and look nothing is dragging. Continue driving and don't seem like is there any more. But it is and is intermitant sometime I can hear it and sometimes I don't. Seems like went away at 40 mph but there was to much road noise to tell. In the middle of my drive to work I heard it again pulling out of a light but then went away again. Get to work stopped at a few stop signs and I don't hear the sound any more. Shamed the exhaust pipe a little with my keys since was still hot when I got to work and I didn't hear anything. WIll see if it does it on way home again after work but don't know what it could be any innput would be greatly appreciated thanks again guys.
