Answers :

This problem\012is commonly caused by a dirty automatic idle speed control valve and\012throttle valve. Buy a can of throttle valve cleaner (do not use\012carburetor spray cleaner!) from NAPA or Carquest (made by CRC\012chemicals) and spray it into the air intake while the engine is\012running, use up about 1/2 the can, engine will try to stall hold the\012speed up, shut it down and let it soak for 30 minutes, restart and\012blow out the remaining fluid, shut it down and disconnect the\012negative battery cable for 5 Min's to reset the base idle control
