okay so my car was already idling around 500 rpms before this but in the last couple weeks it shut off on me twice once going about 45mph and the other at a stop sign (not in the same day), i got told it was the tfi module (ignition module) so i changed that out and it started running horrible, it wont stay on and the rpms jump around, thought it was a bad module, replaced it again and does the same thing, so replaced the spark plugs, ignition coil, checked the shrader valve and gas flowed out of it fine, replaced the battery terminals, and checked the fuel lines for pinched hoses but were fine, i also put a multipurpose cleaner in the fuel tank and now it runs a little longer then before but every time i start the car it acts like it wants to shut off and does and when i mash the gas it acts like it wants to cut off the rpm gauge twitches, after replacing those few parts the idle is around 900 rpms now, but still cutting out and just dont know what else it could be so please help!!! ive been without my car for a week and a half now...

since this has to do with a newer mustang, you'll have better responses on the forum specific to these cars.

Oh no...put the gas back into the shrader valve, quick!
lol
Yeah, our classic's only shrader valves are on the wheels/tires.
We don't need no stinkin shrader valves...
