AnswerWhat's up Doc? (sorry, had to)
Well, you have a bad sensor somewhere. One of the sensors I have been coming across lately is the IAC sensor. Though I think it's call the IAS sensor in a Nissan. Idle Air Speed sensor. I would figure that there should be a check engine light on, but some of the older vehicles that used this type of electronic diagnosing won't necessarily kick on the light. I suggest you take your car down to someone that can scan it for Diagnostic Trouble Codes. There are just to many sensors on that engine for me to have you start throwing parts at it without a direction to head in. Cottman Transmission will scan this for free if there is one near you. Resubmit to me the code numbers and we will "get er done"
