*RPM Surge at idle

Hello everyone, I wanted to ask if anyone has had this issue. I noticed it a few days ago after I came off the freeway. As I was coming to the stoplight - the car's rpm's began surging at low speed and take off. The car turned off when I pulled into the gas station. After filling up; I turned the car on and the rpm's kept going to 1k and almost going down to zero on the gauge. It basically sounds like the motor is huffing and puffing -lol. The MAF was recently replaced along with the fuel pump. I have gotten no check engine light and even hooked up the ODB scanner and nothing came up. Any idea on what might be causing this?

Have you searched for neutral switch? They can cause a similar issue.
