Gl running rough as

[Glynn.]

lately ive been having a bit oftrouble with my gl, engine is not holding a steady idle, using too much fuel, flat spotting at different times, i know for a fact its running rich as we plugged it in to a diagnostics tool, but thats all the info it said
has going to just replace engine temp sensor, but dont know what else it could be
any help would be appreciated

well i replaced the temp sensor, blasted teh crap out of it with some subaru engine head cleaner foam stuff, has gave me my power back no flat spotting etc, altho she still idles rough and no minor backfires.............
