starting issues
so when I drive my vette for a long period of time ( hour or so) when I shut it off and it sits for 20-30 mins sometimes when I go to start it back up it spudders, shakes and stinks and wont fully start.. Ill wait a few minutes , keep trying and the boom it starts. It sounds very unhealthy and I'm really concerned with the issue. My battery seems okay( 12.7 v at rest) and I changed the FOB battery today. think it might be fuel issue or air lock possibly?? it always starts good when its cold. It's really random and seems weird. car is a 2007 Z06 with 20,000 kms on it. it's also supercharged so if the stock fuel pump hasn't been changed I'm thinking that could be a source to the problem as I bought the car with all the mods done. I just got the car and this really sucks. any ideas or suggestions?

Hot start issues can be a difficult problem...as Justasheet knows. Normally adjusting the base idle airflow table takes care of it. It seems to me that the problems tend to happen to those with larger injectors.
I would suggest that you take your car to your tuner for additional base running airflow. I would certainly not start replacing parts.

Yeah I'm booking it in for a computer /dyno run. As the car came from Calgary Alberta where the elevation is in the mountains and air is completely different that where I live in Saskatchewan. So the car is tuned for those surroundings which might also have something to do with it.
