Question about 2003 Toyota Camry
You have a very common problem. You have lost the "base idle" paramater, by changing the battery. What you need to do is drive the car thru several "drive cylces". Drive it in stop & go traffic, stop & let it idle for 2 minutes...then get an the expressway, engage passing gear several times. Pull off somewhere safe, let it idle, and duplicate the cycle again. This will teach the ECU the base idle, and you problem will vanish. We do this every day, for the same issue. Common problem, easy fix.
