Did you replace coils with brand new oem from dealer or aftermarket or used coils? What do OBDII codes read?

Check you MAF connector for good seating and contact.

OEM coilpacks we presume? Why did you replace them?

Hope you didn't pay too much, But I guess this means you will seek a true Senior Infiniti technician.
