I have a 1996 tahoe i keep getting a flashing then goes to a solid cel. Spark and fuel/delivery has been eliminated as problems. Ive noticied it happens more while driving on highway as yesterday driving to work about 30 mins into the drive it started to do it. Last friday i belived i fixed it, it ran fine all weekend and monday.
All the things ove done to it
Noid light all connectors
Fuel pressure test/ leak down
Checked for spark with a tester
Pulled cap off to inspect
Checked for vacume leaks
While driving the code came up and checkes freeze frame it said system a and b has not satisfied conditions to go to a closed loop im thinking that has something to do with it
