ok guys question? did my mechenic do somethin wrong or is somethin else going bad in my gs4.... two days ago had to change out the alternator cause it went bad. now today in the morning I went to turn my car on to let it warm up a little and as I turned it on it idled very low and kind of vibrated pretty hard as if it was gonna turn off, but it was just a matter of a.second and the car was back to normal. it just worried me because it acted as if it would turn of but jumped back to normal instantly. is it normal due to the battery not being fully charged since the alternator wasn't working properly before? thanks for the feedback ahead of.time

Check the voltage of the battery when the car is on and when it's off..

when the car is on, the voltage should read 12 ish..
when the car is off, the voltage should read 13 or even 14.

thanks I will check during my lunch here in about an hour or so

Sounds like a bad battery connection or a bad cell in the battery.

battery puts out perfect charge like you said blktc just came back from checking it. maybe cause its colder now a days ???
