I had my ignition coils replaced about 3 weeks ago and I picked the car up from the dealership. I began to drive and the car felt great, strong through the powerband. I come to a stop sign and the idle becomes very rought and I mean really rough then the car just shuts off. So today I bought a new battery and put it in, my car then begins to shut off again after I drive anywhere and come to a stop. My car stalled at least 5 times......I know this may seem jumble but this is just weird as hell, any help would be great.

Thanks Guys

 

If you're under warranty bring it in ASAP to check it out. If not you should still bring it back since it sounds like it happened right after you picked it up from the dealer and they "fixed it."
