Ok so whenever I stop the STI, whether its in a parking lot or at a stop light, my idle drops all the way down under 500RPMs and the car is extremely quiet but still running. This just started yesterday. Before that the car would hold a solid idle around 1150-1200RPMs (AC off) Anyone have any clue as to what this is and what is causing it?

Vacuum leak or a dirty MAF would be a good starting point.

Lightweight flywheel or lightened crank pulley?

It could, but not necessarily if it's not enough to trip the code and lock it into the ecu
