I just went to start my DB9 after it had been sitting for 3 days and the car is running very rough in the garage, exhaust popping, emissions service message, and solid check engine light.

I read posts here where people had this issue with their vantage, but their car was running normally.

I moved the car around the block and it seemed to be running very rough (it also got extremely cold outside in the time it was parked).

Anyone else have this issue, I will call my dealer tomorrow - but unfortunately, they are 150 miles away.

Also, I am going to go ahead and buy the 3130 scan tool recommended as this seems to be a common issue, just worried about the rough running, car is a 2009 with only about 400 miles.

 

Unfortunately it could be anything - i think a half decent auto shop can pull the codes for you and tell you what it is.

My 06 vantage threw a CEL like that

took it to a gas station, dealt with a sh*tty bitter mechanic but he was able to point out that the front O2 sensors needed replacement

Took it to a Ferrari/Porsche shop and they replaced two front O2 sensors and the problem went away and the car now starts perfectly in the mornings..

The starting got better either due to that or I that moved it to warm(er) place than new england...
