my car is not obd0 is obd1 it's got 3 plugs like any obd1 out there
well for what i know alot of pleople told me it is obd1 3 plugs btw my ecu os jdm p13 4w. do u guys think that the 4w plug is making the car do that ? cause my accord dont have the 4th plug some told me that the 4th plug is for the rear wheel drive steering . u think it may be some damage in my ecu ?
