code 20

MN-Marty

I am flashing a code 20 as well as a code 1. The code one does not concern me, the o2 sensor is an easy fix...I think. But my manual says to take to a shop to check the electrical load. The guy I bought it from said he replaced the main relay. Could the problem be that the ECU was not reset?

Don't think that is it, but just undo your battery for about 30 sec. That will reset your pcm
