So I was driving my mom to Wal-Mart last night. I was sitting at a traffic light in first gear, and noticed my RPM's boncing between 1.5k-500. Then it turned off. But the car started right back up. Has anyone had this problem? There is no check engine light on.

 

I had that problem. It turned out to be my MAF sensor.

 

MAF for me as well. I can't believe how pricey this part is on the Max.
