I recently got the Cleaning Exhaust Filter again and took your advice and ran it till it cleared, I found a back country road and let it go (about 60-70) once the pavement ended (about 20 miles from the point that it came on (the message)) I turned around floored it (hit about 80 in no time) then it cleared I dropped it dow to about 45 and cruised back into town, I didnt see smoke again until this afternoon, I was running a little late so warmup time was cut short (way short) and when I was merging onto a main road I had to get on it and man did it smoke, Fortunately the 17th I am getting new fuel filters (x3), a new exhaust filter, and some other things that the dealer has promised to fix... ( bought it used ). sorry to rant have a great one...:ford:
