I even drove around like a grandma for a month to see if that was the case.

Idling caused initially. It eventually stopped but stayed at a higher RPM than before installation. I haven't seen any improvement in mpg. I even traveled for a month as a grandma to see if it helped and still no result. I contacted the manufacturer to make sure I installed it correctly. He made sure I did. I drive a 2006 gls sonata. As a result, my car stalled and would not start. I removed it and everything is back to normal. upset.

Pros
