I purchased my 2004 G35 about 6 months ago, and now when I run the car for awhile and turn it off, it dies every time I start unless I give it some gas. Cold starts are 100%. I heard it could be dealt with by an ECM Reset or a throttle body cleaning. Does anyone have any experience on whether or not it works? I want to avoid taking it to the dealership as those trips hurt the wallet. Let me know!

Thanks

 

Clean your throttle body.

 

or your MAF sensor
