Hi, i have a 2003 Nissan Altima 2.5s. I have a problem starting it only now that it is cold outside. When the car has been sitting around overnight or for 8 hours while im at work is when my problem accurs. When i start it, it will run very rough for a few seconds, the rpm's surge wildly between 500 - 1100rpm, then cut off. To keep it from cutting out i have to tap the gas pedal in time with the surges so the rpm does not drop too low. I have to give it about 5 taps so that it will stay running. But, after that it runs rough for another minute and tries to keep the idle around 600 or so. Other than that the car is fine.
I am thinking that maybe one of the sensors is not reading that it is cold outside and is not telling the computer to fast idle until the engine is warm.
I find it strange that the fans come on even when the car is cold. Maybe the computer is getting a signal that says the outside temp is warm or hot.
Please help....thanks in advance.
