Default Re: rpm's surging at around 30-50 mph! HELP, Is it the Shi@Ty GAS!

I drove it to work Monday and it does it evern when warm, 1500 to 1800 RPM jumps between them with no change in pedal pressure. I took the throttle body off and cleaned it VERY well Monday evening. Drove to work today... no difference. A leaking manifold would throw a lean code and there are no codes.

Could the throttle body electric motor be causing it? Looking for idea's.
