Troubleshooting stumble at idle in gear

On the subject of plugs without fail every time I tried ACs in a Mopar I got a whine in the speakers that wouldn't go away til I changed them again for champions. So ac is a no go
I've heard good things about autolite plugs, tried em for the 1st time in my dakota only because the place was out of stock for champions.
I have used autolites before just never in a Mopar.
