i just recently got a 1995 chevy z-71, and the check engine light came on, and i took a paper clip and put it in the a and b terminals and the truck showed a code 23 which is A MAT circut or an IAC sensor...What would that mean?

Welcome to AF. Inlet air temp sensor appears to be disconnected or bad, 5.7? I assume.
