I have a 94 Pathfinder with a rough idle that will stall-out when the vehicle is cool (Morning or after sitting for extended periods of time). I've replaced numerous parts on the vehicle: MAF, IAC, Spark Plugs/Wires, CAT, Air/Gas Filter, Several Hoses, O2 Sensor, and Gasket / Hardware on Left Exhaust Manifold (Still need to replace Right Side). Rough Idle is not as noticable when the vechicle is warm/hot. I've read several posts on Rough Idling, but so far have not found the cause. Any thoughts on causes of rough idle?

Haven't replaced the coolant sensor. Were is the coolant sensor on a 94 Pathfinder? Will this sensor effect idling?
