IT sounds like a throttle position sensor (TPS) of a Idle Air Control Valve (IAC). Is the check engine light on?

Hi:
Have you checked fuel pump pressure? Is power normal other than the surge?

If the electrical end is good and fuel pressure is good, the only things left are a vacuum leak or catylatic converter may be plugging. Have you checked for these problems?
