So here is the senerio. i have a civic si with a obd2 harness and a obd1 dizzy. i turn the key, fuel pump primes and the car starts up with no problems and with idle with no issues.. UNTIL i apply the foot break and the cel will turn on, it wont change how the car runs but if i keep my foot on the break it will start to run shakie.
anyone have any opinios on what would cause that. thanks

Code 73 is an OBD2 ECU-specific code but you have an OBD1 ECU. Post a video of the CEL blinking the code.

Are you sure you're running an OBD1 ECU? Post a pic of the ECU.
