I've got a 97 GMC Suburban w/139k miles on it. Just getting home from a trip today when on the way home, the orange 'service engine soon' light came on towards the left side of my dash.
I checked the fluids, all guages look fine and no engine noise with the engine running fine. I had a GM product once where when this light came on, as I recall there was a reset button on my EGR valve that reset the warning light.
Guess I'm hoping to hear from those with some experience with this light and maybe some advice other than taking it to my dealer (since our particular local dealer REALLY hands it to you when you take service work in there.
TIA for any advice.
