For some reason I have noticed during the hotter days I have been having trouble keeping the car running. This happens both on cold starts and hot, and frequently when coming to a stop IF the car hasnt moved much, i.e. slowly moving through a parking lot. Sometimes I'm embarassingly starting the car 3 and 4 times before making i out of where I'm at. Haven't really been able to get a good log of it, but what i do know is if i get up to speed, slowing to a stop isn't really a problem. And when the ambient temps ar 5-10*F lower i don't really have a problem. Which makes me feel like it must be related to intake air temps.
All i can imagine is when i tuned the car it must have just been too cold to translate to good summer behavior. Could this just be a situation of needing more/less idle air?
This is on a 99 LS1 auto.
