My 2007 Corolla is making a "pinging" sound after it runs for about 20 minutes. Sounds like the last few kernels of popcorn popping or the pinging noise you'd hear from under the hood after you turn the car off. It only makes the noise when the car is moving, not when idling at a stoplight. What could this be? Thanks.
