So I went to work Friday and nothing was wrong with my car. I get in it to leave and my check engine light comes and my right front running lights/blinker lights stay on. The right blinker light inside the car is also on. Now my question is how do you pull the codes off the plug? Use a test light? And the car is a 94 lt1 caprice(OBD-1). Any help is greatly appreciated. Please feel free to ask any questions also to try and help you get a better idea of what's going on.
