The "buzzing noise"; I can tell that I am not alone in having this problem but has someone figured out ... I fit does, that eliminates the brake rotors, tires, wheelbearings, CV's etc. ... BUT with an Altima it is probable the pre-cats. Loud humming noise when driving

Wheel nuts loose, or stones in hub caps, do you get the noise rolling down hill ? , if not its engine, retrace your repair.

1. HOW MANY MILES ON VEHICLE
2.REPAIR & MAINTENANCE HISTORY
3. ANY PRE EVENTS THAT MAY BE RELATED

Hi Kate,sounds like your valves need adjusting,here's a link on how to do it.Here's how you remove the valve cover.

I took my car to Keller's Auto Repair in Gettysburg PA, He specializes in Chryslers. I have 04 Cruiser with 2.4 Turbo that had the same whistle noise, and check engine light on. He found code P0301. The noise was caused by the #1 Cylinder injector O ring. Check them out on facebook. They will help you.

they had some problems with the throttle bodys on thiem could be the couse if the check engine light is on will need the codes taken out to be sure

Nissan Altima 2003 and up have timing chains and if you have looked for them you're not going to find it unless you take the valve cover off and you will see it on the left side but be thankful for one thing that Nissan guarantees that the timing chain will last the life of the engine which is about 250,000 miles. but as anything mech. it can go out anytime new or old have this checked out soon along with the oil pressure let me know what engine you have and the millage email me and ill do some research for you Lee

I just had the same problem with my '02 altima SE.
Took it to Buckeye Nissan in Hilliard OH. and they had to replace the two crank sensors which.
The sensors themselves were about $44.00 a piece, but w/labor about $300.00 was the total. Hope this helps.....Now if I can just get the heater working!

we need to make sure your car is going into overdrive.
as long as your 60 mph isnt stop and go and its an extended drive over 30 miles you have a problem
and i assume your engine light isnt on
