Yesterday, replaced battery due to no cold cranking amps. Today, driving,cutoff

assuming everything was ok prior to this repair, it will need an idle relearn. Roy

Hmmm, if the battery was disconnected for a long time (more than an hour) yes. Fire up the vehicle, let it warm, then drive the crap out of it! You will have it die at lights/stops. After a few, it will re-learn everything. Same issue on 2007 SX-4 and 2001 and 2002 Vitara.
