I know this aint a mustang v6, but its a 87 thunderbird with a 3.8 v6 and it has TBI (throttlebody injection) My mom drives the car but she says that when the car is not warm it will studder and die when she starts coming to a complete start. When the car gets warm/hot it drives fine and dosnt have that problem. I cleaned out the throttlebody with BG intake/tb cleaner a few months ago and after that it never had that problem. but the same problem came back. Changed the fuel filter and the car got new plugs last year. Any ideas why that would happen?? I dont even know if i can pull codes on this T-Bird, never tryed. please help. thanks
no, i havent seen any lights come on yet, i drove it today and it drove fine for me. Ill clean out the trottlebody with intake cleaner and run the car and it seems fine. my mom says it stumbles when she hits the breaks. but today i didnt notice anything.

Stumbling when you first hit the brakes sounds like the IAC. It could be sticking and as long as the motor it self is OK it won't throw a code, even if the plunger sticks.
