Runs slow until warms up

I have '96 GXE Altima with 100K in it. No warning lights or anything. But, in cold weather when I start the car - it just does not feel like running. But, if I let it warm up for about 2 or 3 minutes and when the temp gauge goes over 'C' - it runs ok. I tried driving after a little warm up and still it seems to be lacking driving power. Recently (for last 3 months) have been using '91 and '93 octane all the time and even put in fuel injector cleaners. Has not helped.

Any suggestions?

Any CEL?
Sounds like in open loop. Check oxysen sensors.
Also any list any modications.
