About 2 years ago I purchased a 1995 Nissan Altima with 132,000 miles on it,
since then I have ran it up to about 172,000 miles.  The car drives ok but
there are some things bugging me with it.  First let me tell you what I have
replaced.  So far I have replaced the plugs, wire and distributor, the
battery and alternator, both CV halfshafts, the flex pipe and cat convertor,
both O2 sensors, the radiator, thermostat and water pump and the tires. I
have changed the air filter and oil every 3,000 miles since buying the car
although I don't use synthetic because there is seepage at the pan and valve
cover gasket.

Now here is what the problem is, I dont' know if it is supposed to be this
way but the steering feels loose to me, it seems that I have to constantly
make adjustments to keep the car going straight, and when I turn the wheel
it feels like I am moving the steering wheel about an inch or so before the
wheels turn.  I have had the lower ball joints and tie rods looked at and
was told they are in good shape, what can I do about this problem?

Also, only when I am stopped and idleing the RPMs seem to fluctuate and it
feels like the car is misfiring randomly at diff cylinders.  It is an auto
if that helps. But I can't figure out how to fix this, the car is fine while
moving and accelerating just at idle it does this.  And only in the winter
time when it is cold when I first start the car up for the day it wants to
sort of chug forward in short sporadic bursts but when it does this i just
stop and rev the motor a bit in park or neutral and it fixes the problem.

When I brake somtimes the cruise control light flashes but only when I have
cruise on and not activated.  It doesnt do this every time I brake but only
does it sometimes and never while driving only braking.

Finally, the trunk seems to be leaking when it rains but I cant find a
problem with the gasket and also the light fixtures look to have this black
seal all around them.

Any help with these problems would be greatly appreciated as I do like this
car and don't want to get rid of it.
