I do not know anything about the Pathfinder, but most unlikely to be ECU unless it is a known problem ie bad batch of units etc, more likely are the information inputs to the ECU like MAF, Crank position sensor, injector lift sensor etc, Rick

Why did you have the ECU replaced?

Was the replacement brand new or second hand, is it possible the replacement is not the correct type for your car. As said normally its a sensor rather than the ECU.

Is there a manual in the downloads section for the Pathfinder? Or a manual for another vehicle with the same engine perhaps.

Best of luck
