Hi

My 10v 95 idles 1100rpm on cold start and settles to 900rpm when warm. The 93 GLT would idle slightly slower.

I am guessing that the tacho is not so accurate, as 'Bill of Durham' writes. As long as it isn't surging or stumbling I don't think it's too bad.

Just some additional info:
On my car there is an vacuum operated valve in the airbox, and 2 small tubes connected that provide the suction. I think that these are not likely to go bad.
(it's an '98 s70)

FCP should not be listing that part for turbo 850s. Turbos don't have an airbox thermostat. I'll send them a note.
