04-26-20 THROTTLE PEDAL RESPONSE ON TIP-IN

Publication Date: December 23, 2004

FORD: 2004-2005 Explorer
MERCURY: 2004-2005 Mountaineer


This article supersedes TSB 04-22-5 to update applications.

ISSUE:
Some 2004-2005 Explorer 4dr and Mountaineer vehicles built before 10/4/2004 with a 4.0L engine, or before 12/14/2004 with a 4.6L engine, may exhibit issues related to the throttle pedal response on tip-ins from a stop and on deceleration tip-ins.

ACTION:
Reprogram the powertrain control module (PCM) to the latest calibration level using WDS release B34.9, or B35.1 and higher. Calibration files may also be obtained at Motorcraft.

NOTE: THIS NEW CALIBRATION IS NOT INCLUDED IN THE B35 CD.



NOTE: THROTTLE PEDAL RESPONSE WITH ELECTRONIC THROTTLE CONTROL (ETC) DIFFERS FROM RESPONSE WITH A THROTTLE CABLE. REPROGRAMMING THE PCM WILL IMPROVE, BUT MAY NOT ELIMINATE, THIS CONDITION.

1. Go get a new throttle body gasket and can of throttle body cleaner. Remove and clean your TB.

$10

2. Pay $100 for an PCM update, which may still leave you needing to do #1 .

I cleaned my TB and it fixed the issue for me.

Oil enters the TB and builds up just enough a layer that it causes the TB to stick.
