My verano runs great until I stop. When I step on the gas to go it will die. No engine lights. It will start immediately after the stall but won't go slow. I have to coax it to keep it going then it will run fine until I stop????

What is your question?

There is no noise or any warning at all. It doesn't happen all the time. Seems to happen most when its been running for a while.

What makes this problem better or worse?

after its warm
