The pulsing isn't normal, First off put a code reader on your engine and see if you have any codes. If not then I would spay some fuel injection into the throttle body and see it that helps, spray it down good while the engine is running. If that doesn't help clean the air bypass valve, or your throttle positioning sensor is bad.
