I would get vehicle on a scanner and check live data.
could be a faulty coil pack or injector on cylinder 4. Try putting the coil pack from cylinder 4 onto cylinder 1 and rescan.
If the fault moves to cylinder 1 the coil pack you moved is at fault.
You may have to replace the whole coil pack if individual units are not used on your vehicle.
The injector process is same as above but a bit more tricky due to the fuel pressure in the line...be careful!
If swapping these has no effect you wil have to carry out a compression check on all cylinders and see howthey look against cyl 4.
The shaking is the misfire, the smoke is unburnt fuel.
Dont drive it in this condition you will destroy the catalytic convertor.
I assume the vehicle has a regular service and the spark plugs are in good condition.
note...when this prob is resolved..change the oil and filter, it will be contaminated by now.

SOURCE: 2000 CIVIC System too lean Cylinder 3 and 4 misfire Deteced

  1. P0171: This means that the oxygen sensor has detected a lean air-fuel ratio. This can be caused due to a vaccuum leak or a problem in the HO2S circuit or the HO2S (Heated Oxygen Sensor) itself. (Bank one Sensor one). This is commonly located along the exhaust pipe. It could also be a bad Mass Air Flow sensor or a bad Engine Coolant Temperature sensor. Diagnostic checks will be needed to be carried out to be verified though
  2. Well as for the other codes, it means #3&4 cylinders are misfiring. It is a possibility that the P0171 code mite have caused the others to show up. I can be wrong though. But it is a strong possibility. If the air fuel mixtue is too lean indeed, mis-firing will occur, unless it is an actual electronic and not a mechnical problem. By the way, when these codes appear, how is the engine's performance. Does it remain the same or behaves poorly?

SOURCE: replacement of a head gasket on 2.5 liter nissan altima 2002

frajogag: First off, be aware that these bolts are "torque to yield" bolts (streach bolts). What this means is that instead of torqueing the head bolts to a specific torque specification, they are torqued down to a set spec and then tightened by rotating the bolts a certain angle, like 90 degrees. and all of them are turned the same amount.
This means that the shanks of the bolts must be checked to make sure they are not too thin (or the bolt has already stretched beyond limits and is prone to snap if used)
Here is how you check the bolts. Measure the bolt using a micrometer, at the base, or within the first 13mm from the end where it threads in. Then go to about 10mm before the threads end heading toward the top of the bolt. There should not be more than a 0.23mm (.0091 inch) or less difference or the bolt should be discarded.
Torque the bolts down to 98.1Nm ( 72.ft lb)
Looking at the head from the side, so you are looking at the full length from side to side, I will number the head bolts in this fashion.
#1 & 2 are directly in front of you and in the center of the cylinder head crossing it width wise.
#3&4 are to the left of #1&2, / #5&6 are to the right of #1&2
#7&8 are to the left of #3&4 / #9$10 are to the right of #5&6
Now, you have the sequence.
After the initial pull, back off all the bolts in the same sequence and then retorque them to 36 Nm ( 28 ft lb)
Using a torque angle wrench or having the ability to accurately judge turning angles. Rotate (clockwise) to a 75 degree angle. do this to all the bolts using the sequence I had provided.
Rotate the bolts (clockwise) 75 degrees again on all bolts in the same sequence. The proceedure is complete!

SOURCE: nissan altima 2002 burning excesive oil what to

You have to identify where the oil is leaking. Check the spark plugs if it has oil, you may just need to replace the oil seal in the plugs. If you meant actual burning from the exhaust, you may want to check the head gasket and the piston rings if the oil seeps into the combustion chamber.

Just replaced valve covers on Nissan Maxima 2002 due to misfire. Now it smokes and burns oil every start? What's should I do .


If is is only smoking when you first start it up. Most likely the valve guide seals, oil is leaking into the cylinders and smoking when you start it up.

well black smoke means you are burning up engine oil. low idle means you have less compression. you might want to check your gaskets! does th engine oil level go down after a drive?

2009 nissan sentra using 1 qt of oil a week and computer says only misfire cylinder 3 what gives?


Take it to the dealership if it's under 60k miles. If it's sucking oil, then it sounds like you might have a bad head gasket, which is covered under the warranty. There's been a lot of hinky issues with the 2009 Sentra and #3 cylinder misfires, but apparently they don't want to do a recall on them. It's almost as if they're betting on the problem developing after the warranty expires.

White smoke occasionally coming out of my Altima tail pipes.


If there is no loss of Coolant, which is a sign of Head gasket failure to the combustion area, which generates white smoke, I would recommend after 4000 miles of your mileage alone, a complete Service of Engine Oil and filter, AIR filter and Fuel filter.
An inexpensive way to find a recurring combustion problem, At 60k miles, the Spark plugs should still be good, but pull them anyway, just to confirm.

2002 altima burns oil about a quart every 300 miles. I Just got this car engine is very clean . I had oil changed and they talked me into haveing an oil flush ran through the engine with the oil change....


Check your muffler, is it thick black? The engine is burning oil, you need new engine if the cylinder ring is bad (compression test), and new catalytic converter that poisoned by excessive oil.

Many altima 02 has pre-catalytic converter failure that cover under 8 years/80k miles emission law. The materials in the pre-cat destroy the engine. It is well known problem and you can get new engine under this warranty
