Hey, I have a 94z with the mods in my sig. Last week my SES light came on out of nowhere. The funny thing about it is if I stop at a Stoplight and the car is not moving for anywhere between 15-25 seconds the light will go off, but as soon as I give the car gas and start moving the light immediately lights back up. Does anyone have any idea what could be causing this? I've never witnessed any other Ses Lights doing the same thing as mine. All help is appreciated.

 

Take the car to some local shop and have it scanned. Or maybe you can post in the regional forum and find someone local with a laptop and a cable who could scan it for you.
There are so many possibilities that it's really hard (or simply not worth it) to find out the code by guessing.

 

He's right, get is checked for stored codes. 10:1 it's the EGR. Just a wild guess though.
