I have an 88 rx-7 turbo and it was having problems starting while it was warm, and now it just shuts off while its idoling. it seems as if its not getting fuel, and when its idling its not staedy and the idle very low. I just put this theremo sensor thing on it that this guy said regulates fuel flow to the engine while its hot, and that it might be bad and blocking fuel, but it didnt help

If u have any ideas or could at least point me in the right didrection i need it. i dont really know much engine crap so im pretty dumb.
