Does this sound like a vacuum leak?

When I apply the brakes while not moving, RPMs surge a few hundred or so.
Then the same thing when I let the brake off.
Also noticed the rpm fluctuates slightly (about 100) at idle when I watch the tach.

sounds like a TPS problem.
"The TPS is located on the throttle body at the end of the thottle shaft. By monitoring the output voltage from the TPS, the PCM can determine fuel delivery based on throttle valve angle (Driver Demand). A broken or loosen throttle position sensor can cause intermittant bursts of fuel from the injectors and an unstable idle b/c of the PCM thinks the throttle is moving."
I have the Instructiosn for testing the TPS, if u need them email me Joe dksob81@hotmail.com
