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
1. 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.
2. 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.
3. 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.
NOTE:
PCM REPLACEMENT IS NOT AUTHORIZED BY THIS TSB. REFER TO THE POWERTRAIN CONTROL/EMISSIONS DIAGNOSIS (PC/ED) SERVICE MANUAL FOR APPROPRIATE DIAGNOSTIC PROCEDURES IF PCM HARDWARE CONCERNS EXIST.
Obtain an Authorized Modification 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.
