Anyone have their instrument panel turn off and then turn back on. Motor keeps running no problem there. Will get Check Gauges light on and sometimes this light will come on but the guages will still work properly. and other times the Check Guages lite will come on then the panel switches off then back on. Don't know if this is a pcm problem or not.

 

Might just be a bad ground....

 

a bad ground is usually the culprit but which ground, Surely someone out there has run into this one before.
