I went out and came back from a drive across town. The temp was around ~202*F. I rev'd it a bit before I shut it off like I usually do, and it caught and diesaled a bit around 800rpm before it died.... Is this something i should be worried about. Its pretty blatant that either the injectors were leaking or there was some residual gas or something...

 

So is this "diesaling" AFTER you turned the key off? That would be a new one, lol...

 

Turned to ACC, there shouldn't have been any power to the coils. I'll maybe my wiring mess finaly is starting to screw me or something.

 

I know that term well. Also known as "run-on" or "after-run". I've a few cars that would do that now and again, but never heard of it with a rotary.

 

as long as the motor is spinning, the coils will fire, only diff is that the alternator is shut off, as well as the fuel pump.
its a common flooding prevention technique, turn the key off, then floor the car and let the fuel rail empty out.
how long were you able to "diesel" it?
