Car stutters and cuts off

[Josejoe]

Okay so I had this problem in my spyder and now on my gst. (Both automatic ) and when I'm switching gears and have my foot on the break the car begins to shake intensely and then cuts off. It happened in my spyder but went away and was no where near as intense as the gst. Any ideas?

lightweight flywheel?

bov not recirculated?

It's all stock both cars. It just stutters and shuts off

check the brake booster hose from your intake?

I would also check the plugs if it is stuttering that bad it would be miss firing

So it stalls, then what? Starts back up? How's it running at idle?i would be looking at the booster or vacuum lines. See if booster is working can pump it up then start engine the pedal should go down further and have assist.

Could also get some carb cleaner and spry it around the lines. if there is any fluctuation in idle rpm you have some bad lines and need to be replaced

first thing i would do if i where you is disconnect and properly reconnect ALL vacuum hoses. when air escapes your car will act like that. if that doesnt work make sure your fuel pump is working by turning the key to ACC and listen to see if your pump makes a low tone. i gotta go im already late but i will be back to check up on you. keep me updated
