clean your MAF ... A dirty mass air meter can cause a rough idle, decreased performance, and computer codes among other problems. Most can be cleaned with spray electrical contact cleaner.
if you still have problems, clean out your TB with carb cleaner
my alero is doin the same thing when its cold in the morning. My idle bounces pretty good. I just put a cold air intake on my car and did a tuneup like 1,000 miles ago. I'm thinking about using the induction cleaner to clean my throttle body and intake mani. Not sure if anyone else has any info on how to fix this
thanks agan ill use the contact cleaner on the maf. and clean out the tb and see what happens. im not going to tune it up, my brother did that before i got it, new fule rail and injectors, and he had the intake proted $$$$$$$$$$ lots. i got a good deal
but it dose not like to run when tis cold. 
it has a rough idle, between 500 and 800 rpm, any ideas
