Buick Regal 3.8 dies while braking

My 1993 Buick Regal 3.8 V6 dies while I am braking. It only happens when the engine is warm and the engine is under light or no load and (what makes me really confused) if I put the car in neutral it starts right up. Any idea what might cause this?

    The problem has been solved, it was over heating.

    Oh my God, i'm having the same problem. Mine is a '93 Regal Custom (3.1). She's fine cold but when brought up to standard operating temp (she's not overheating) she dies when i slow down and/or idle. I have 2 keep her up over 2k rpm for her not to die. I went ahead and did a tuneup (plugs, wires, oil change, all filters, pcv valve) and it improved a little. The only filter i bought but didn't replace is the fuel filter, but i doubt that's the issue. I also cleaned out the egr valve (a new one costs almost 200.00) and again, it helped just a little. A new or cleaned out egr might work 4u. I think the reason it didn't 4 me is because my car sat for a year on a farm and there's some kind of fuzz in my crankcase where the egr bolts on. There was a mouse's nest in my air filter when i got her...If u get any answers please share!!! Thanks, Jake (Jacqueline) Adams

    I had a similar problem where my 93 Buick Regal would die when decelerating but would start right back up afterwards. I took it to the mechanic and they replaced the fuel pump and filter, which did the trick.

Check to see if you have a lot of dirt in the throttle body. Clean the throttle blades out with brake cleaner or throttle body cleaner. You'll see alot of dirt come out. Keep spraying until it comes out fairly clear and wipe the throttle body out with a rag. If this doesn't do it, you may have a problem with the throttle position sensor (TPS). This sensor controls the idle after the car warms up and keeps it from dying when you brake or sit at idle.

I never use that stuff, but you can put it in the purge valve or map sensor port or even the port for the hvac control system. Just dont use the brake booster port, or the engine will die.

Idle position switch or sensor. I had 93 that would stall when i came to a stop. Cost me $43 but it was worth it. I don't know if this will fix it, but it sounds like it would.
