I have a 93' 1.8 ltr Escort with a Check Engine light on. I'm told the DIAGNOSIS box is from MAZDA. Anyone in the MAZDA world know how to pull the codes from it? My Ford code reader is no good to me. Can I jump a couple pins in the box to read flashing lights? The CEL started as being intermitant, when it would go out, I could feel it stutter, then carry on down the road. It don't run real bad right now but I'm sure it could be better. It has a new O2 sensor. Don't want to throw any more parts at it till I know what's up.
