I have a 1994 Pontiac grand am 4 cyclinder and engine light is on. I looked up how to test the obd but nothing is working. The connector only has 3 pins. 2 pins on top left and 1 pin bottom left.
How do I go about testing it. It does not have any other pins just the 3 on left side of connector
If need a picture I can get that
Thank s very much
have the same problem?
