Default odd semi-surge
Hey all...

I'm getting a slight "surge" when cruising along around 55 MPH. It bounces up & down between 1500-1700 RPM with my foot lightly on the gas.

Weird thing is she idles perfectly fine.

I'm thinkin it's because I upped the tires to 37s? Am I on the right track or are there other theories?

Thanks!
