how is the idle relearn procedure??? or it will adjust while I drive the car across the days??
it will correct itself given time, but correct procedure is....
disconnect battery for 15 mins
DO NOT TOUCH ANY PEDALS
key to ign on, (as in all idiot lights on) wait 40 seconds
Won't be perfect running, idle will be close to 750 rpm ish but will get better as fuel trims sort themselves out over the next 10 or so trips.
The bigger question is why are you changing the battery all the time?
I average 4-5 years out of a battery here. You are not doing the car any favours changing it all the time as every time you do it has to start at the default ECM values and relearn all the ABS sensor offsets, ESP and yaw sensor calibrations, steering angle sensor and fuel trims.
