I got my 94 cougar 4.6L on the road. The check engine light is on. So I took it to work and used the Auto X-ray to scan the codes. I hooked it up to the ODBII looking connector inside under the passenger side dash. I used all 3 different color plugs with the scanner. Every time I got vehicle not responding! So is there something I'm doing wrong, or is there a different plug because its a 94? Isn't 94 obdI? I will add that the air bag light was on so I pulled the bulb yes it beeps at me. Could this be why the engine light is on? The car runs great, idles nice and smooth.
