SOURCE: Hi, I have, 2001 Nissan Maxima.

renew the O2 sensors to start with and just hope that its a bad sensor on this bank they can break down prematurely .Luck of the draw their when buying new parts iam afraid your not the only one to buy new parts and have them go early .

SOURCE: I have a 2000 nissan Maxima. trouble codes are:

Hi, the car is winding out due to a vacuum leak. Not sure if the misfire is related or not. I would start at cylinder 1, though. I would check all vacuum lines attached to the intake manifold, especially around #1. Replace any cracked or hardened hoses. If all lines are good, then I would check for an intake manifold leak. With the engine idling, spray some carb cleaner on the intake gaskets especially around cylinder #1. If the engine speed changes, you have a leaky gasket. If none of these ideas panned out, I would start checking the purge valve and other valves along the lines that attach to the intake manifold, but this sounds like a pretty big leak you should find quickly. Please let me know if you have questions or need any instructions, and thanks for using fixya.

SOURCE: i got a code that

You obviously do not know or care about your truck,
as far as OBD2 dash lights being on

When ever you get any diagnostic trouble fault codes
& thus the dash lights,your vehicle has problems

These lights have been on all vehicles for 31 years
Plenty of time to educate yourself

You get the code now & have somehow found out
possible causes,as you would if you went to a trouble chart

So you off to a good start,just a year late

I wouldn't even worry about the injectors,the gas filter is
taking care of them

You could put a pressure gauge on the system, to check
fuel pressure. Should do that every couple years anyway

Your O2 Sensors, the one or two closest to the engine,not the
rear monitors,get replaced every 100,000 miles

The MAF Sensor gets cleaned at least once a year

With a Lean Condition on only one Bank I would look for vacuum leaks
You may have to have the intake manifold smoke tested & check all
vacuum hoses & sources.

Don't rule out a misfire on cyl#1

As far as resolving anything,you didn't say if you have the
ability to do some of your own work
You obviously don't take it to a repair shop,at least not in a year !!
