i chanced upon this forum because i am looking for explorer owners who have same problem as mine....burnt smell during hard acceleration...3.4 to 4k rpm. My EX (delivered april 2012) has been in and out of casa coz of this problem. Casa guys already performed a couple of TSBs but failed to eliminate the smell, but reduce it only. Casa guys are working with Ford plant guys but until now they seem at a loss. Perhaps, dragon explorer has found a solution thru your dealer?I read your thread in explorer forum. I hope Ford guys come up with a fix soon before i decide to ditch the car for other brands. Tsk tsk...meantime, if we are on same plight, lets join hands and bring this matter up to Ford Philippine top management...is that the Krieger tall guy?
