I hade this proble on my 86. It may not be your same problem but check the connection plugs on your secondary injectors the heat from the engine worped the connectors preventing a tight fit so they would come loose and at about 4500 rpm the car would bog cause of lak of fuel.. or your secondary injector are bad
