did an engine swap, stock d16a6 on a 90 si.

after the swap we had these codes and car runs poorly.

car starts when throttle is part way down, and have to keep on the throttle. idle also hunts. when you rev the engine the engine hunts while revving.

we changed the ignitor, same problem.

we reset the pcm as well.

we plugged in another iac and it had the same problem, no response to the iac.

any help will be appreciated.
