I have an 04 Expedition, Today 60 degrees, dry last 4 days other than frost in am...... Started car drove 200 miles- was 34 when started the day.... made it almost home, ABS Light came on, followed by Check Advancetrac. Vehicle drove fine.. drove another 30 miles. Turned car off.... Restarted no lights... made it another 2 miles ABS light and check Advancetrac back on.... Home restarted lights still on. drove half a block vehicle started bucking and stalling... Attempted to turn off Advancetrac... made no difference.... at one point had gas pedal almost to floor, acted as it does on snow and ice...... Any ideas on where to start? Any ideas greatly appreciated... Thanks!
