Q: Throttle body or sensor issue

asked by on October 25, 2016

My Chevy aveo has issues when it's cold, it starts and runs for about 5 seconds and than turns off, I try again, it doesn't turn on at all. Once the weather warms up, around noon it turns on, no problem. I took it to the mechanic and he said it may be a throttle body or a sensor, idk which sensor I need to replace. Should I clean the throttle body or have a new one put in?

My car has 58000 miles.
My car has an automatic transmission.
