Check Engine light

[Arthur Alewine]

The light comes on and off regularly as you are riding down the road. Where is the diagnostics hook up on a 1993 explorer XLT.

The port will be next to the fuse block inside the engine bay, close to the a/c blower box

mine was doing that for awhile.... turned out one of the water hoses had a tiny crack in it, and was dripping/spraying small amounts of coolant all over a sensor, when it built up enough pressure. after i repaired the hose, the light didnt come on again
