ok well first off i have to tell you that my alt belt squeels like a pig when i first start it cuz its real loose gonna change it this weekend. but i also have a problem with the car shutting off. it only happens once in a while at only at idle like at stop lights signs etc. I don't know why cuz it starts right back up after it dies please help.

 

try the IACV but if it isnt that often I wonder what exactly is causing it
