thanks to you both for probably perfect answer to my mystery of what happened after putting in new Costco battery yesterday for our 2006 MZ5 5MT -- warm idle fluctuating erratically between 500-750 rpm, almost stalling. The above is certainly worth a try. I'm heading out to try it right after dinner.
 
PS -- the Mazda OEM positive battery cable end was shockingly weak, I completely ruined it overtightening trying to get a solid connection to the new battery. But a new connector, labeled "marine", costing less than $5 from O'Reilly's was an easy fit after some filing to enlarge the bolt-hole, and adding some washers.

and the new "marine" battery cable connector is about 10 times stronger than the OEM one. I'll live with the few-ounces weight penalty sapping my gas mileage, thanks.
