ISSUE
Some 1999 - 2001 Escort ZX2 Coupe vehicles equipped with a 2.0L Zetec 4V engine may exhibit spark knock during acceleration. This may be caused by the Powertrain Control Module (PCM) calibration.
ACTION
If spark knock condition is verified and normal diagnostics cannot pinpoint condition, reprogram the PCM to the latest level calibration. Refer to the following PCM Calibration Information Chart.
Obtain an Authorized Modifications Decal (FPS 8262 - obtainable through DOES II, 25/pkg) and list the date, dealer number, and summary of modifications performed. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized Modifications Decal. Clean the area, install the decal, and cover it with a clear plastic decal shield.
