cam gear recall went wrong
drop my car of 2 weeks ago for the recall they had the car for 7 days once i get to dealership i had to wait an hour for them to pull the car up to the front, the guy said the car wasn't turning on, i dont know if they left the car unplug or they left something on and it killed my battery, once i got the car back i started driving home, once the car was all the way warmed up i notice my idle wasn't as smooth as before, when the car is in gear it idles at 500 and when the fan comes on it shakes a lil and drops to 400, i call my advisor i explain to him my problem, he said because the battery was unplugged it take few miles for the car to relearn how to idle, so i kept on driving, next day it was doing the same thing this time behind the light the rpm kept going from 500 to 600 jumping up and down i did lot of research, few said it could be the battery going bad tested the battery and the battery puts out 14.1 while driving, than i look on CL and found this tech tip

I'd start by giving it a few more days, as it takes a little while for all of the system to re-learn everything. I can tell you this though...after I got mine back from the cam gear recall, I disconnected the battery again. Let it sit for 10 minutes to idle, and then took it out for a 20 minute drive for it to re-learn my driving style. All as well thereafter.

^That hestitation is the "new way" the car re-learned to shift. Disconnect the battery for 30 minute, then re-connect and go out and drive like you would. I force mine to re-learn hard downshifts in 6th gear down to 3rd or fourth about 10 times. After that, it's usually good-to-go thereafter.
