Folks, Check engine light came on. I have a scanner but no trouble
codes show up.
Here's the thing: light comes on intermittently, mostly at slow speeds
like in the city; on the highway it goes off and stays off.
Light comes on at start, after some minutes it goes out, but comes on
again when idling or starting from red light. There is no obvious
engine problem that I can see or hear or feel when driving. Anything I
can look for before going to the dealer? I checked the gas cap.
1996 Volvo 850 gle wagon.
Thanks!

Could be a transmission (non-OBD-II) code. Had this on my 850 a year or
so ago.
