stuck injector, misfire, or coolant thermostat broken are usual causes of the raw gas smell.

A stuck or leaking injector would leak fuel into the cyl.head......no smell, there is no F..in way the thermostat could cause a smell either. An external fuel leak,however would cause low fuel pressure at the injectors....low power and fuel smell the injectors require 50 PSI, and the fuel lines are not monitored by the PCM, trouble codes low presure will also cause poor idle, and evidently you have a circuit problem to the IAC
