When i go start my car up in the morning in this cold weather(ever since it dropped to below 60 overnight) its been having a real rough time btwn 900-1000rpm, almost to the point of stalling it seems. but just btwn 900-1000. the whole car shimmies and shakes, but since i dont drive or idle through that rpm, im not that worried about it, but it could be a concern im guessing.

any thoughts?

bump, anyone?

Have you replaced the throttle position sensor?

My guess is the IAC.

the shimmy and a lil shakin...i too noticed this on my 98 at times...it doesnt happen everyday but sometimes.
sometimes in the cold and or drivin a bit...i was thinkin maybe a dirty fuel injector,or fuel filter,or some stupid sensor

My guess is the IAC.
