I was cruzing around today because it was a nice weather and I park for a little bit and I some how touch my accelerator pedal and I notice that the rpms went down and then up I tought I was seeing things so I did it again and I notice that rpms went down and then up when I touch the gas pedal
.
This is the first time that I has happen does anyone know what may be the problem
When I bought it it had vaccum leaks and I replace the mass airflow sensor and the air intake boot and I seal other vaccum leaks but never change the idle control valve I have no idea if that's the problem

Clean the idle control valve and make sure your Throttle Position Switch (TPS) under the throttle body is working correctly.
