My mom has a 2001 Camaro V6 automatic. When she was at a stoplight yesterday she said the idle got low and when she went to go the car stalled. She said you have to have one foot on the brake and give it a little gas to get moving. I know next to nothing about Camaros or Chevys in general. Does anybody know what it could be? Thanks for any help.

it had a leak from the EGR valve...
