My moms 01 has this code active and stored, so I know it's a definite problem. Sometimes when driving the car, you come to a stop, the rps drop to about 500 and feels like it's going to cut off but it doesn't and it goes away, just like that. I read the troubleshooting manual and it lists all of the following as possible causes: CPS; igntion coil/module; and or wiring in the ignition circuit. I just don't know where to start looking. I'm thinking if it were a defective coil, then it should throw a misfiring code for that cylinder. Any help you guys can offer would be greatly appreciated.

 

I believe that you have a ignition coil gone bad... To test this.. warm up the car and while its running pull the coil out, the one that doesnt affect the engine idle is bad... Thats what my car did with a bad ignition coil.. once you know which one is bad, Dave B or Coursey Nissan can hook you up for about $50-65...

 

Yeah I thought about trying this. Thanks.
