welcome to the forum, how long since a tune-up? I'd take the throttle-body off and clean it, also, check the iac and tps sensors. Have the trouble codes checked. Some of the national brand autostores used to check codes for free. you might call them and ask.

Were you having the problem before the battery and alternator replacement? Even if the parts are good, if there is a problem with the wiring circuit, somewhere, it will still cause problems.

No problems before they went out. Does the computer on the car need reset?

After battery power is lost, the computer may need some time to relearn engine run parameters. In our database, I didn' see a particular relearn procedure for your vehicle. Just by driving the vehicle, it should relearn on its own?

I got the car to idle by letting run for about 10min. Thank you for helping me with my problem.
