Sputters while idling, ideas?

Yeah, I will send you one. I just dropped a brand new MAF sensor in it. No change.
Car runs well at idle. A little miss in it. Really acts up going down the road.
Video in a few minutes.
Put a code reader on it. Multiple misfires on multiple cylinders. Coil pack. And fuel issues according to what came up.
Cannot really hear what it is doing in the video. But it has a slight miss at idle. Going down the road it backfires and sputters badly. The new MAF sensor is helping it maintain speed, but it still pops and sputters. Does not quit running at idle or stop lights.
Going to check the injectors next.

Thanks for the video, are the spark plugs OEM? They must be one of the following spark plugs:

NGK Single Platinum Tipped

Standard Type FR5AP-10
Cold Type FR6AP-10
Hot Type FR4AP-10
NGK Double Platinum Tipped

Standard Type PFR5G-11
Cold Type PFR6G-11
Hot Type PFR4G-11

Any other spark plug will cause a misfire, also did you replace the plug wires with OEM as well? Also when you did the distributor did you replace the ignition coil?

The plugs are the NGK single platinum suggested for the car.

The P0180 is for a fuel temp sensor. You need to resolve that issue whether it be the sensor itself or a wiring issue and ten is you still have the problem, monitor the fuel pressure while the problem is occurring.

I took the distributor apart. Cleaned the magnets in the ignition module. The sputtering and backfiring stopped.
Now, it idles at 11k. Closer to 15 when cold. Doing the new wires today. We will see. The spark from the old ones is yellow. Hoping the ECM is just trying to compensate for poor fire.

I would do the wires and the idle should relearn in a few miles of driving. Have you serviced the throttle body?

Be a good idea as well.

My 2000 nissan xterra is turning on ok and I can drive it for a while and it is fine. Then all of a sudden it starts to sputter out and wants to stall. I changed the spark plugs and air filter and added some fuel injector cleaner but it has not solved the problem. I am leaning towards replacing the IAC Idol air control? I need some advice thank you.

Do you have a check engine light on and when was the last tune-up?

Could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it and keep testing.

Good job, have you driven it to see if the idle has calmed down?

The engine begins to shudder and try to cut off after driving 8 or 10 miles.I can keep it going for a while if I continue to rev it up, but if I really get on it it will stall out. Is this the distributor?

Hi Greg,

If keeping the accelerator pressure on it runs, then it could be the idling system, spark plugs, coil packs or fuel injectors that need attention.

If it fails to respond at high speed or rpm while driving, it should be the fuel system, either the fuel filter is clogged, pump is weak or thr regulator is faulty.
