Question about 2002 Cadillac Deville
From your air filter follow that black intake hose to its end, there is a clamp at the end. That's where your throttle body is located, its like a trap door/flap/butterfly. Make sure you are using intake cleaner and a clean rag to spray and wipe clean Open flap can be done by pressing on gas pedal(may need help with this) keep open and spray into throttle body , when this is sticking most of the time the flap/butterfly is very very dirty fully of a black greasy gummy substance. when clean it should return to its original color of metal. Good Luck contact if you need more help
