WARNING: This modification is authorized only for the listed engine. Performing this modification on other engine calibrations is unauthorized and could create liability under applicable federal or local laws.

ISSUE

The Malfunction Indicator Lamp (MiL) may illuminate on vehicles with a 4.6L or 5.4L engine, and one or more of the following concerns may be present:

MIL lamp on with Diagnostic Trouble Codes (DTCs): P0133, P0135, P0141, P0153, P0155, P0161, P1130, P1131, P1132, P1137, P1138, P1150, P1151, P1152, P1157, P1158
Rough idle
Engine miss
Hesitation/Surge
Buck/Jerk
Stall at idle
Near stall
Stall at low speeds

This may be caused by the Heated Exhaust Gas Oxygen (HEGO) monitor calibration not allowing enough time for proper monitoring.

ACTION

Reprogram the Powertrain Control Module (PCM) and replace the HEGO sensor(s). Refer to the following SERVICE PROCEDURE for details.

SERVICE PROCEDURE

Perform normal diagnostics as outlined in the 1997 Powertrain Control/Emissions Diagnosis (PC/ED) On-Board Diagnostics II (OBD II) Service Manual and repair as required.
If the concern still exists or no problems were found, reprogram the PCM using Service Bay Diagnostic System (SDBS) or New Generation Star (NGS) Tester. Refer to the following RECALIBRATION CROSS REFERENCE CHART for correct PCM calibration.
Replace the HEGO sensor(s) (F88Z-9F472-AB) as required.

NOTE: For 5.4L applications, dealers must also perform TSB 97-26-17 to install the drain tube on the lower A/C evaporator drain.
