LOL...I see where the confusion is now.

What I did was took the part number off the sensor directly....

GMRLS1IAC

Which I found here....

I know it's not an LS1, but for my engine a lot of the sensors trade straight over. The IAC, the MAP, the knock sensor, etc. When trying to amtch them up at the time, I just found it easier to ask for 98 camaro....

I used the IAC part number because that ended up being the part that fixed it... I had never seen one go bad, but talk about an expensive trouble! burned 3/4 tank of gas getting to the launch ramp...(about 6 miles)
