96 GT dying when braking

Hey guys I need help. I have a 96 GT automatic. It doesn't do this all of the time it just does it every once in a while. My car dies when you are braking. I am stumped by this and cannot tell what the problem is. I took it too a transmission shop and they also couldn't tell me. I replace the iac, the camshaft position sensor. Any other ideas I'm at a loss

Thanks in advance

You haven't changed anything at all? No cai or anything?

Easiest way to find a vacuum leak is get carb cleaner and spray around the intake and vacuum lines. But it can be tricky since yours is doing it while braking. What about sitting still and hitting the brake? Does it die then?

Since its dying while braking id say brake booster ....however we have a hydroboost so not an option. However i agree i would spray carb cleaner and listen for a rev up pr death of the motor.

Well I thought it was a transmission problem because it felt like it was pulling while I was braking. But to no avail. While its at an idle it runs fine. It only dies when I'm driving and coming to a stop. The weird thing is though that it doesn't do it at every stop. It only does it once in a while.

Clean the MAF, IAC, and throttle body. Also a loose battery connection can cause what your describing. My v6 used to do that and come to find out I had a bad cable that was loosing connection.

I would still look for a leak like vacuum leak or a cracked manifold

Vacuum leaks towards positive pressure i.e. atm pressure so it can be a leak in vacuum if its supposed to be maintained at say 25hg vacuum but leaks out to atmosphere then its a leak. Now that im dine ranting lol have u checked your tps sensor. It may be possible that the throttle sensor is doing it as well. We have so far eliminated iac due to it being replaced however maf is still possible since it hasnt been changed but tps can cause it too. My guess maybe get a junkyard maf sensor from a crown vic or mark 8 if u are my years. I say mark 8 cause its the same maf as 96-98 just calibration to 24lbs. However ba k to the point its to eliminate things before we try to find a crack in the manifold witg a fog machine.

Or buy a maf new try it then return it if it didnt work and get the money back

Okay replaced tps this afternoon. Not a help. I'm thinking ill replace the maf this weekend. Have to wait for school to let out. I am only 18 so funds are also limited. Hahah. I might try the junkyard maf. We have a pull-a-part that I used to go to quite often. It helped familiarize me with engines. Thanks again for the feedback.
