My 03 coupe with 120k and M6 has some starting issues. On occasion when I start my car, it shuts off right away. I will have to give it some gas once it starts so it doesn't stall on me.

Any idea why this is happening?

 

dirty MAF?
my car used to do that but once i got the MAF replaced it stopped.

 

x2 deffinitely the first thing to try is to clean the mass air flow sensor

 

Cleaned the MAF today, hopefully this fixed the issue. Seems like this is the cause as I have a k&n as well which seems to be why the MAF gets dirty.
Thanks!!

 

K&N caused it without a doubt.
I bought an Amsoil filter for the G35 and another car..
both car needed the MAF cleaned/replaced within a month
