I have a 1998 Toyota Camry with about 180,000 miles on it.  I have had
relatively no problems with this car until recently.  When I start the
car and the engine is cold it starts idling roughly like the engine is
going to cut out.  It only idles roughly for about 5 minutes or until
the car is warmed up.  It doesn't idle roughly if you put it in
neutral instead of drive or reverse.  Does anyone have any idea what
this could be a transmission problem or some sort of low flud?  I am
not almost out of gas.  Please reply if anyone knows what I should
start troubleshooting.  I just thought it was wierd that it doesn't do
it when it's in neutral.

Thanks,
Brant
