If you are like me, and your altima's idle is bad/shaky, then look here.
Here it is:
Nissan Technical Bulletin No.NTB93-117
Take this bulletin to a nissan dealership and hand them this information written down on paper.
"The Altima’s 2.4-liter 4-cyclinder engine has had problems with a rough idle (vibration) which is transmitted through the steering wheel, seat and floorboards when the transmission is in drive and the brakes applied. There’s a detailed idle speed adjustment procedure which has eliminated the condition on a number of vehicles, and this needs to be performed by a qualified technician"
no. you'll probably get charged an hour of labor.
I took my 97 altima in with that bulletin number, and they pointed out that I should get my engine mounts fixed first. You may want to have your engine mounts fixed. My brother's 99 altima had problems with that too.
You got me. That is a question for the dealership's service department. Please post what the dealership says. You may want to have your distributor looked at. I've read that the distributor could be causing the shake. Have the engine mounts looked at. I am getting all 4 of mine swapped out for $400.
your distributor could be doing it but the more common problem for all of this (and this service bulletin looks to be just a cover up of it) is a vacuum leak. Normally this occurs in the intake gasket. Turning your idle up a bit will only compensate for the problem until the leak gets worse. This is not always the case but the easiest way to test for this problem is to spray carb clean around the intake manifold when the idle is "rough" and if it smooths/evens out at any point then you have an intake gasket leak at that point that it smoothed out (test a few times at that spot to make sure that its correct and wasn't just a smooth spot in the idle). Unfortunately with our motor it seems to be a fairly common problem as is the oil in the distributor cap, but that'll cause some rough idle, bad driving and then quit altogether on ya. I hope this helps you out a bit.

EDIT: its highly unlikely that this specific bulliten deals with manual transmissions because of the use of the work "drive" normally if a TSB is meant to include both transmissions it will use the word "gear" because there is no drive on a manual tranny. But this problem does occur with both types of trannys.

I managed to do all of mine but the transmission mount myself for less than $150. You can get the mount on the passenger side for $50 at Autozone or Oreillys. The others are $20 & $30 respectively (ish).

my altima shakes on idle, too. and the rpm is not steady. i changed out all my motor mounts and tranny mount last summer.
so I spray where the manifold meets the head, or where the manifold meets the throttle body? or both? is there other things that can cause the vibration? vacuum hoses all checked out. the freakin shakin of the steering wheel is annoying as crap....
