Red brake and yellow ABS trouble lights go on and off several times a day. They are on about half the time. Also check engine light stays on or turns off for days at a time. GM Dealer checked everything and re-grounded electrical system. This seemed to help, but only for a week, and all the lights are back on again intermittantly. Now dealer says check engine evap code may be dirty vent tube but not sure. And they could start replacing things beginning with the "black box" that controlls the trouble lights. But this is an expensive part and labor intensive ( >$1000. repair) Please suggest possible sources of trouble lights and what order to start replacing things? FYI - both front hubs had to be replaced recently but evidently was not related because it did not help.
