1999 Dodge Durango Stalling

When you have an engine problem you need to state which engine you have. Oil pressure is not monitored by the Engine Computer and low pressure will not shut the engine down. As proof of that, some drivers don't understand that they are supposed to stop the engine immediately when there is no oil pressure. They keep driving and cause serious damage to the engine, then wonder what happened.

If your oil pressure gauge drops off suddenly, especially at idle, and comes back up suddenly, suspect a defective sending unit. That was a fairly common problem along with the gauges reading unusually low at idle speeds.

For intermittent stalling the place to start is by reading the diagnostic fault codes. If there is one that mentions the camshaft position sensor or crankshaft position sensor, that is the circuit that needs further diagnosis.

Stalling when approaching a stop has a real common cause and easy fix, but if the engine also stalled while you were driving at a steady speed, that doesn't apply. Most commonly the crankshaft position sensor is the cause but typically the engine will not restart until that sensor cools down for about a half hour. If there are no fault codes, your mechanic can drive with a scanner connected and record the event when it occurs. The problem is getting it to occur. Later he can replay the data slowly to see what changed when the stalling occurred.
