So i just got my car out of the body shop couple days ago and went to turn it on today and wouldnt start. The time i started up it fired up but then died (dies right away when rpm drops). Tried again several times same thing happen. Finally when i gave it gas it started up. I noticed the last time i change my spark plugs one of them was covered in oil. Its an '03 G35 Sports Coupe. Can anyone help me out i would appriciate it thanks!!
