I have a 2006 Pontiac Grand Prix 3.8L V6. So the
problem is when I got to hit the brakes the car
wants to sound like it's shutting off but it's doesn't
completely shut off. It just start to go into a really
low idle. What is the problem

Clean your theottle body out qith a scrub brush really good. when you open the valve you should notice a black ring where it closes. air coming past that keeps the car from stallin at low idle. If its sealed with carbon this will happen
Scan for trouble codes. That's always a good place to start. ( Plus its my favorite answer)
