See you're pre 03, just unplug brain under hood, leave the "brick" on top of carb and use the big knurled thumb screw for idle. Unless you're comepletely bone stock, I hope you re-jetted for our Michigan winters
Ya, you're good with just unplugging the brain. Ya, it's nice today and could be 0* tomorrow. Atleast bone stock jetting isn't quite as big of a deal, you should be safe to about 25. When you're modded it does become more of an issue.
