SOURCE: 2001 nissan altima is sputtering and misfiring, I

have you checked the spark plug wires? try changing those. sometimes they can get a little crack in the insulation which can cause it not to get full spark to the spark plugs

SOURCE: Rough Idle or stall when stop or slowing down.

COULD HAVE FAULTY FUEL PUMP.FAULTY MASS AIR FLOW SENSOR,FAULTY EGR VALVE WILL STALL OUT ENGINE.I WOULD GET VECHICLE CODE SCAN BEFORE BUYING NEW PARTS.

SOURCE: 1999 nissan frontier is idling rough the truck

This can be your Idle control valve, when you turn the air on it puts the engine under load and your computer will increase the idle automatically to prevent the engine from cutting out.
When you are standing still and the car is shaking, by touching the accelerator very softly does the shaking stop? If so check the idle control valve.
I hope this will help.

SOURCE: My 2000 Nissan Frontier has sputtering problems

your tach is run by the engine computer, possible cause. also by the crankshaft position sensor, most likely cause, I would start there. some sensors will run within perimeters and be bad enough to cause a lot of problems

SOURCE: I have a 95 nissan sentra and it keeps idling

Check vacuum leaks , by spraying carburator cleaner around intake manifold gasket and vacuum hoses connections . See if engine picks up the idle speed while you doing it , and if it does , locate leak and fix it. Most common , intake manifold gasket brakes.
