Advancetrac light in my 05 expedition king ranch can't get it to go off

What is your question?

at 50 mphrpms go up but truck speed climbs slow then the traction kicks back in anybody know if the advancetrac would cause this and what to fix it

What makes this problem better or worse?

Worse after warms

How long has your 2005 Ford Expedition had this problem?

Since I bought it last month
