It's the sensor in the rear of the intake. It's in good shape and was working when taken out of a 99 T/A. LS1 intake was replaced with an LS6 that already had a sensor. Part # 16212460 over 81731298 Delco sensor.

I'll hold it, your first in line. Just let me know. Also you have the mail you requested in pm.

Buyer fell through, if anyone wants it, let me know. Can work on the price a little.

How about whoever wants it, just pay for a round about shipping charge?
