lol, you know what i mean by "cold"

59F is considered cold around here

im pretty sure there HAS to be a way to adjust the idle on a UCF21, this is something il look into. (anyone have a 98-00 LS repair manual i can browse thru pls

)

ok, so.... the problem had NOTHING to do with ignition or air/fuel mixture. I finally took the car to the dealer and they told me I have a broken motor mount, with the other one getting close to breaking. They suggested replacing both motor mounts as well as the tranny mount... for $850. Alot of money, but will be nice to have a smooth running ls again.
