Hesitation During Acceleration
ACTION:
A new idle air by-pass service kit (F2PZ-9F939-A) is now available for service use to correct sludge contamination concerns of the throttle
bore and plate only. It eliminates the need to clean the majority of past model throttle body applications. Cleaning is not required on sludge
tolerant throttle body designs released for 1991 and newer model years.
Figure 1
Install an idle air by-pass service kit (F2PZ-9F939-A) as applicable to provide a permanent correction for symptoms caused by throttle body sludge
deposits. Refer to the instruction sheet included in the kit for installation details. Refer to Figure 1 for a specific application list of EFI (port fuel
Injection) engines involved in this TSB article.
