i'm currently having problem with my 1997 obd2 del sol with a obd2 b20 motor. it was running fine til my brother moved out of state and had a person worked on it.now its running rich. i try to get a hold of that person to back track what he did but he can not be located.

so my plan is to totally convert all the harness from the inside of the cabin to the motor to a obd1 (93-95).

does anybody knows what all have to do to convert? can i just get the harness behind the dash with the engine harness too?

needing some advice. thanks

 

If you're wanting to convert to OBD1 you don't need to change out dash harnesses just get an OBD2-1 ECU adapter. I don't think thats going to fix your running rich problem however. What has been worked on? What engine and ECU do you have now? Have you done any tune up items (plugs, wires, cap, rotor, etc)? Checked ignition timing? Any check engine lights on?

 

correction i'm using a b20 obd1 with a obd2 to obd1 conversion harness.everything been check.but there's a cel for map sensor.
