When I first drive my car from cold I have a problem with the revs dropping below about 800rpm.Its almost like the engine is about to stall.Sometimes it will eventually come right, but usually I have to use a bit of accelerator to increase the revs. I also notice this when Im slowing down approaching traffic lights and I put the car in neutral, the revs drop really low and the car takes a while to adjust. I have put a Cone Style AirFilter on, no other mods. Any ideas what the problem could be, maybe a good tune or something. Is it normal?
The first thing that comes to mind is that your base idle may need to be reset. This is a common symptom of the base idle being too low (revs drop and come back up). It could also be an issue with your AAC valve. Of course it could be other things.

Here is the best tune-up guide for the SR20DE:

I think something has loosened up a bit much from the rougher ride that the low profile tyres have. It is almost like an engine mount is loose, but ive had them checked and they are apparently all fine. Any ideas or common problems with attachments coming loose around the fire wall or back of the engine?
Do you get a buzzing noise when you get off the throttle? The front engine mount (driver side for you) is a common problem on the Sentra SE-R (B13 with the SR20DE). I've heard little problems with the P10, but it's possible. What happens is when the engine is decelerating, it rocks, and if the front engine mount is bad, it can contact the coachwork and make a terrible buzzing racket.

I don't know if this is the problem you are having, but it's a possibility.
