SOURCE: 2001 nissan altima idle surges
I had same problem.It turned out to be intake gasket.If it surges when u come to stop or in park, u may want to look at corners of intake,spray something that burns around intake , if the idle levels out it is gasket.

Won't idle after battery change... SOLVED! well, for me anyway. :)
I just experienced the same problem on my 2002 tundra last night, and fixed it this morning after sleeping on the problem. Here's how it went.
I cleaned the terminals, etc., and replaced the battery, as it was 7yo and old and on the verge of failing.
Immediately after this, the truck would start right up but the idle would drop to about 100 RPM, then slower and slower, and eventually stall. Every time.
I warmed it up and drove around the neighborhood for about 45 minutes, thinking the computer needed to re-learn it's Idle settings, etc... No change.
This morning, I decided to go after the cheap and easy fixes first...
Inspect throttle body... it was filthy full of black sticky dirty/sludgy stuff. I cleaned it off using a rag and some brake cleaner. DID NOT spray brake cleaner IN the opening; just on the rag and then wiped all of the gunk out of the opening, butterfly, and inside as far as my fingers would reach with the butterfly open.
Reassembled everything, started truck... runs perfectly.
Dead battery? Won't run? Dirty throttle body? How do these all tie together?! Here's why (to the best of my understanding).
Over the past 65k miles, dirt and gunk slowly but surely builds up in the throttle body. At some point, the computer senses that this affects the air/fuel mixture or something of this nature. The computer compensates for this, and stores it to it's memory. Sometime during the vehicles lifetime, the battery fails or is disconnected. The compensation settings that the computer stored are lost when the power is disconnected, so the next time the engine is started it's telling everything to behave as default... but the car isn't in a default state, there's **** in the throttle body... or a bad sensor, etc.
I could be way off, but my gut feeling is that this is correct. My advice: Pull the intake tube off the front of the engine and clean the gunk out of the throttle body. It should be the first thing to try, since it's the cheapest and easiest thing that I can think of.

There is a relay on the rh passenger side kick panel above the automatic transmission module that is controlled by the ECU through the MAF sensor that controls your fuel to the engine so the air / fuel mixture is correct. I fixed a pathfinder one time with a similar stalling problem.

Clean your Throttle body and pay attention to the Idle Air Control (IAC) valve passageway to try to clean the IAC. A dirty or faulty IAC will cause your engine to stall at idle, the job of the IAC is to open the passage way through the throttle body to regulate the amount of air to enter the engine to keep it from stalling when the Envoy is at idle.
Start with the simple and clean the throttle body and inspect any loose or damaged wire leads to the throttle body. Replace or repair any signs of damage.
Thank you for using Fixya and good luck.

You can retrieve the trouble codes from your '94 Nissan Pathfinder right from your home garage, saving yourself both time and money. 1994 Nissan Pathfinders come equipped with an on-board diagnostics 1 computer (OBD 1) that retrieves and stores all trouble codes sent to it from various sensors. When these sensors detect a problem, they send the code to the computer. The computer illuminates service and/or warning lights on the instrument cluster. You can retrieve these codes using a handheld device called an OBD I code reader. This can be purchased online or at any auto parts retailer.(I have OBD-2 and bought a V-checker brand reader, don't know if they sell an OBD-1 reader or not. Alternatively...
The Quick Paper Clip Test
It should be mentioned that a quick method to see which trouble code or codes are being set in your cars ECM is to jumper the A and B pins of the 12 pin ALDL (assembly line data link) OBD1 connector with a paper clip. While the car is off, sitting still, turn the ignition key forward while this jumper is in place. Do not start the car. The Service Engine Soon ( SES ) light will flash in a repeating sequence, telling which trouble codes have been set in the ECM. A service manual for your year car will have a chart outlining what each trouble code stands for, or this Trouble Code website can be of help. Some vehicles have an OBD2 style 16 pin connector but still have OBD1 behind them. Disclaimer: I don't know if this will work on your vehicle and you will be proceeding at your own risk. I'm not responsible for any work you do or have done to your vehicle.
