here goes, i have a 90 lx, in the past we tried using a scan tool to figure out some codes and other issues (a good friend of mine is a licenced mechanic and has all the fancy gadgets) but could not get anything on the tool. seems the connector isnt working. have any of you heard of this? possible causes? fixes? i want to get the car tuned, but i want to make sure all sensors are working before i
