1998 Mitsubishi Diamante stalled while driving
Check timing belt first. Some engines are interference types, such that when belt fails pistons may hit the valves causing major damage. Google search you engine # to see if your is or is not one of these. If non-interference type, you will just need to replace the belt, but most folks also replace the belt tensioner and perhaps water pump if it is also belt driven. You normally buy a kit of all these parts.

1998 mitsubishi diamante o2 sensor, o2 heater, EGR sys NOT READY
Check the O2 sensor heaters with an ohmmeter. Also test the EGR solenoid valve by applying 12 vdc directly to the solenoid pins.
Disconnect the HO2S.
- Measure the resistance between PWR and GND terminals of the sensor. Resistance should be approximately 6 ohms at 68°F (20°C). If resistance is not within specification, the sensor's heater element is faulty.
- With the HO2S connected and engine running, measure the voltage with a Digital Volt-Ohmmeter (DVOM) between terminals HO2S and SIG RTN(GND) of the oxygen sensor connector. Voltage should fluctuate between 0.01-1.0 volts. If voltage fluctuation is slow or voltage is not within specification, the sensor may be faulty.
