That's the idle air control. Or IAC sensor. Not sure but I think 92 did not have it there and it started there in 93. They might have sent you the wrong one. -

Jim, that is the intake air temp. sensor( IAT), and I suspect you have the wrong intake rubber duct. Keith the IAC is to the left of ( IAT )sensor.New England chapter member, 63 Convert. 327/340- Chapter/Regional/national Top Flight, 72 coupe- chapter and regional Top Flight.Comment

Both 1992 and 1993 used the same sensor. It was originally GM #25037352 and is currently GM #12160244, aka Delco 213-243.
The intake duct for 1992 and 1993 was the same and included the same sensor. The duct was originally GM #25099598 but it's been GM-discontinued and is scarce.
The duct you have been supplied is incorrect. I don't know what year model it's for but it's not 1992 or 1993. I believe that 1994 and later went to a MAF sensor and used a completely different duct which would not begin to fit on a 1992-93.
In my opinion, you definitely need the sensor. Without it, I expect you'll have a constant "service engine soon" light illuminated.In Appreciation of John HinckleyComment
