Car turns off when I stop or slow down (92 Cadillac Deville)?

[Keith H]

While driving at a decent speed there's no problem but when I begin to slow down car makes a jerking motion and turns off. It also turns off when I stop and while turning. Need help ASAP. This is my only form of transportation. Any suggestion feel free to leave comment.

I believe you've got a vacuum problem. If it was your fuel filter you
would also be having problems at higher speeds which you don't.

Look over all of those connections and check the hoses for any
cracks that may have split open from dry rot.

Just my opinion here.

I had a cadillac that did this also. The problem was the torq converter in the transmission.

You need a tune up most likely. New fuel filter, air filter, spark plugs, wires, cap and rotor. Its a maintenece thing that should be done every few years, and should cost about 150-200 dollars at a shop, or for about 60 if you do it yourself. Sounds like its starving for gas when you slow down, and stalling. Start with the fuel filter and see if that does it, but for maintence, do the whole tune up.
