If the engine was out of a automatic car - the IAC will be different from the standard transmissioned ones and could be causing your greif. The Manual transmissioned IAC's are on the back of the intake and the automatic IAC's are on the throttle body. Which do you have and what transmission? If you are using a obd2 to obd 1 adaptor did you pull the wiring out of the donor car and reinstall it in your 4dr? Otherwise why the adaptor?
