my check engine light comes on at startup. I tried taking it to my local auto parts store, but they claim they can't see a place to plug in a reader. So my first question is, does anyone know where the port for the reader is on a 94 ford thunderbird? Any ideas what could be causing the check engine light to come on at startup? I can disconnect the battery, and the light will go off for a few days, and then randomly at startup it will come back on. Engine seems to be running fine. No jerking, stalling, or vibrations that I notice. Any ideas on my problem, or the location of the port for the reader? Thanks.
have the same problem?
