What is the normal idle speed for a jap 1995 wrx.

Mine is 700 rpm which seems to hve lowered since fitting decat downpipe.

 

I have a 96 WRX which idles at 700ish but I have noticed that sometimes when the engine is at running temp slowing down and dipping the clutch it can drop to 500 and then raise back up to 700.
It has never cut out so I am not really too worried.
Does that sound normal?

Mine does the same too.. (MY98 Sti) dunno if its normal but the car seem to run fine

 

That happens to mine.
The thing is i only noticed it recently, so i'm concerned something is not quite right

 

I would love to know the answer, I fitted a new downpipe to MY97 STI TYPE R (IMPORT) and the revs are all over the place, thought it was due to a faulty MAF sensor, but not really sure.
