Your lock settings were most probably changed from your remote unit. By pressing both lock and unlock keys together for around two to three seconds you can switch between silent mode and horn mode. Hooe that helps...

I DONT THINK ITS YOUR CAT OR ELSE YOU WOULD OF DEFINITELY RECEIVED A CHECK ENGINE LIGHT CODE. MIGHT JUST BE SOMETHING ON YOUR SUSPENSION SYSTEM.

Things to check
Plugs;
Remove the spark plugs and read them, they should all have a dry tip and be clean from any carbon, oil or fuel.
Usually if burning fuel properly they will have a brown or whitish looking tint from burned carbon.

If any of the plugs look wet or black or dirty looking different from the others the problem is with that cylinder, change all the plugs and see if that helps, the next lease expensive thing is replacing the plug wires.If your fouling plugs ask your parts store for 1 number hotter plug ( heat range)

Plug Wires;
Open the hood at night with the engine running and see if you find any blue looking arcing around or in the wires, if so replace the wires.

Fuel Injectors
If all above looks good your fuel injectors might be dirty or one might not be working. You could try an injector cleaner mixed in with your gas

A rough idle comes from one or more cylinders not firing as hard as the others or not at all, there are so many causes for this so you have to troubleshoot with the lease expensive fix first.

Another thing is water in the gas, you can pour plain ole rubbing alcohol in your gas tank if you suspect water in your gas. alcohol mixes with the water and makes it burn instead of mis firing.

Valves
One more thing that can cause rough idle is your valves, this requires a compression check on each cylinder. If one cylinder has less compression than the rest remove the compression tester and squirt some engine oil in the cylinder then re test, if the compression increases it is bad rings or a bad cylinder bore, if not it is a valve problem.

Oil seals around the piston increasing the compression temporarily while testing but makes no difference in testing if the valves are leaking.

Good Luck,... troubleshooting and patience, or a good mechanic is the solution if you are working with neither

Use Nissan Altima Automatic Transmission Fluid and it should hold about 10 quarts total. I would fill with 9 quarts and start the engine and circulate the fluid. Check the fluid level and add what you need.

what is the car doing?? by you saing "need a ECM diagram?" what is the problem with the car. that car is pretty bulletproof and I have't seen any ECM issues unless your A/C drain is clogged up and water leaked onto/into your ECM frying it up. Let me know what your symptoms are.

You might want to try and reverse flush the heater matrix. This is the small radiator within the heater. To do this find the two hoses that lead away from the engine compartment to the bulkhead of the car. Undo them both from whatever joints you can find, you will get some coolant loss. Get a garden hose and turn on the water and allow the water to push through the matrix. Do this in both directions ie into both of the loose hoses then reconnect the original hoses top up the coolant, Don't forget to add antifreeze and hopefully a working heater.

I also have a 2009 Nissan Altima and after sitting or driving in the rain the entire back floorboards are soaked. I took it in last year and supposedly they replaced a "plug". Unfortunately the repair was done at the end of the rainy season so everything seemed to be okay. Fast forward to this seasons first real rain and again soaked floorboards. I went back to the dealership very frustrated with the whole situation. This time they had had my car for 4days and I was told that the HVAC box was leaking due to a clogged line. The line was cleared and sealants used on certain areas. The service advisor is confident that this will take care of my problem. I'm not so confident since my HVAC system was not in use when the car was just sitting there filling up with water. Wish me luck. I am curious how many 2009 Altima's are having this problem and if Nissan is just trying to avoid some sort of recall notification. Very dissapointed 1st time Nissan owner.

Ignore me if I am wrong, but I believe the timing is ECU defined and non-adjustable. To confirm, it has a crank position sensor.

You need a body control computer, which controls the windows, door locks and other items. The new computer will have to be programed by a good imports shop or Nissan dealer.

There are atleast 2 fuse boxes in most vehicle's one in the cab typically under the dash somewhere and one in the engine compartment the exact layout of the fuses and relay's in this boxes depends on the make and model of the car but diagrams detailing the layouts can be found in the owners manual. Good luck

VERY interesting ... Rodney2764,

I HAVE seen similar issues before...

Everything else seems to be good. I would be
thinking about having an EXHAUST shop look
for a loose MUFFLER baffle or collapsing
CATALYTIC CONVERTER...

A rusted or loose part inside can COMPLETELY
block EXHAUST OUTFLOW...

It is not a COMMON trouble... but certainly worth
the look (while you are mobile (my opinion...
RATHER than WASTING time & money
buying A WHOLE lot of UNNECESSARY oxygen
sensors
( get mistakenly replaced )...

(( from "FREE" code readings )).

((( really difficult to resolve when you are immobile ))).

Hope this helps...
