That's all it says is "air circuit" ?!

Only thing I could come up with in Google was

Code 61- Air conditioning circuit performance: Check A/C system for possible low pressure in R134A freon.

This was coming from a site who listed F-Bodys 92-95 with TPI though lol

It should give a number at least. Do it the old fashioned way with a paper clip and count the check engine light flashes

I think the paper clip only works on 93's which would be correct in your case Formula350. I am thinking air circuit is the AIR pump.
