Confirmed Fix:
Repaired Engine Control Module (ECM) Wiring
 
Problem Description:
The engine misfires and runs bad very intermittently. It took 2 weeks for the misfire to return after a reset. If one tugged on the wiring harness at the Engine Control Module (ECM,) the engine would run rough. Cut open the wiring harness close to the ECM and the Light Green/White wire on pin #26 appeared OK, but when pulled on separately from the others it appeared the wiring inside the insulation was broken. Repaired the break in the wiring and all of the problems have been repaired.

Confirmed Fix:
Replaced Radiator Outlet Temperature Sensor
 
Problem Description:
The engine has overheated and this caused the radiator to blow out. Replaced the radiator, thermostat and tested the radiator fan operation. The radiator fan would not operate off of engine temperature but ran fine when the A/C was operated.
Replaced the lower radiator hose temperature sensor and the fan operated normally with engine temperature. Had trouble bleeding the heater core to get interior heat. It was necessary to replace the reservoir bleeder valve and all problems have been fixed.

Confirmed Fix:
Repaired Antilock Brake System (ABS) Control Module Connector
 
Problem Description:
Vehicle came in with an intermittent rough idle. Inspected and tested the O2 sensors, Manifold Absolute Pressure (MAP) sensors, and ignition. There were no vacuum leaks found. There was 1 code found. P1261 for Vehicle Speed Sensor (VSS) erratic. Inspected and tested the VSS and it tested good. Sometimes when the problem happened the speedometer would bounce up and down a little when the vehicle was parked and not moving. The tachometer was very erratic when the problem was there. When the problem happened both O2 sensors would go dead lean down to 2.50 volts and stay there and not move. The O2 sensors should go from 2.50 volts to 3.50 volts on these vehicles. Cleared all codes and went for a test drive and code P1261 came back and the vehicle would intermittently have a rough idle. Noticed all data in the Engine Control Module (ECM) was good. Went to the Anti-lock Brake (ABS) module and found it to be reading the vehicle to be going 200kph when this happened. Problem was water intrusion into the ABS module through the connector in to the module. Replaced the module, removed the wires out of the pigtail and cleaned them, and put some dielectric grease in the connector. The computer was reprogrammed and the vehicle was a confirmed fix. It was explained to me the computer was unable to interrupt the information correctly and was shutting down 4 injectors as it did not want to go 200kph.
