Conversation Between randyb and paulrog1

Hi, I could do with some help, I have just installed the new coil packs on my DB9, but the engine is running lumpy with the engine light on and a message saying Emission System Service Required. Did you experience this when you installed your coil packs? I am sure everything is back together ok. Did you reset any codes with an OBDII reader?
I've got a topic going on UK pistonheads Aston Martin if you want to read it.
Thanks Paul.
