My 95 2-door Yukon has a SES light Ghost! Here is the scenario...

-Start truck
-Drive Truck
-After 1-3 minutes the SES light will come one for less than 30 seconds
-Truck is ODB 1 and will not store a code!
-tried driving with scanner hooked up
-scanner shows no codes are stored EVEN WITH SES LIGHT ON!!!!!

This happens 4 out of 5 times... it is not constant.

Any Ideas?
This may be a key to the ol' girl passing California Smog!
