  • IDLE – HIGH IDLE SPEEDS – THROTTLE STICKS AFTER STEADY STATE DRIVING IN COLD AMBIENT TEMPERATURES – VEHICLES BUILT THROUGH 12/1/97 EQUIPPED WITH 4.6L ENGINE
Publication Date: OCTOBER 13, 1998

LIGHT TRUCK:
1997-1998 EXPEDITION, F-150, F-250 LD

ISSUE:

The vehicles identified in this TSB article should be equipped with an insulated PCV tube that was installed in production or under Recall 96S59. This insulation provides protection from PCV backflow due to ice in the PCV system created during steady speed driving in extremely cold weather. In those extreme cases where the insulated PCV tube does not completely eliminate throttle body icing due to PCV backflow, a service kit has been developed that will make these vehicles even less susceptible to PCV freezing.

ACTION:

Verify that the condition is not caused by throttle body sludging, throttle cable binding, or interference between an improperly positioned floor mat and accelerator pedal. If no other conditions are identified, replace the PCV hose and throttle body adapter provided with the appropriate service kit. Refer to the Instruction Sheet included in the kit for installation details.
