Thats a wiring problem.

First check and make sure the A12 and A14 are jumped together on the obd2 to obd1 conversion harness.

Second, check continuity on the IACV signal wire (black/blue) with a multimeter, Check from IACV connector to ECU connector obviously.

Do both these things correctly and you will find your problem.
