Most likely not.  Try making up a ground strap (length of say 12 gauge
wire or so with a wire eyelet on each end) and place one end under one
of the 2 bolts (or nuts, it's too late to run out and look, LOL) on
the hood hinge bracket near the antenna (be sure to put it on the hood
side of things, not the firewall mounting point) and then bolt the
other end of the strap to a decent grounding point on the firewall.
Be sure to scuff the areas a bit to allow for good `grounding' at each
end.

What you're doing is in a sense `grounding' (there's another term for
it and I forget it) the hood to the rest of the vehicle.  It has
something to do with the reception believe it or not.  There was a
bulletin years ago about this on the Pathfinders when I worked at
Nissan.  Sorry but I don't have that one either.  :-(  At least I
remembered the fix.  ;-)

well I went out today and added a ground wire as suggested and it seemed to
help a little bit but the stations I listen to still dont come in as well as
when Im in other vehicles....any other suggestions would be great.
Thanks,

A couple of obvious suggestions...

Is the antenna fully plugged into the radio?

Is the antenna cable bad?  You can check with an ohmmeter for
continuity from the antenna itself to the plug.  Check also to be sure
you don't have a short between antenna and ground.

Is you antenna extending?  My '94 pathfinder has an electric antenna
that goes up when the radio is on.  Is yours going up?

Anyway, my radio seems to work pretty good.  I've had to fix it a few
times, but never because of weak signal.  I had the display go out,
the amplifier fail and the CD player lock up.  I do own a copy of the
service manual.
