Condition

Some customers may comment on an engine idle flair when the clutch is depressed. Also, some customers may comment on a low speed engine decel stall when coming to a stop.

Cause

The flair may be caused by the vehicle entering stall saver mode when the clutch is depressed. The low speed engine decel stall is produced by an interaction between the engine control software and the AC motor.

Correction

Reprogram the PCM with the latest calibration available. The new calibration will be released beginning with TIS satellite data update version 6.0 for 2004 available June 2004. As always, make sure your TECH 2(R) is updated with the latest software version.
