Question type: Maintenance & Repair

I have an 04 trailblazer I changed the coils but they are not ACDelco brand could it be that that is making my car run rough and wanting to stall when idle at a light or anywhere ? It has stalled a few times but started right back up thank you maybe also the map senor ?

On the I6 engine coil brand doesn't matter, plus yes, use only AC Delco 41-103. If your idle is bad at a stop light, is it still bad if you put it in park or neutral?
