Hi gang,
First post. Very informative group.
As the subject says, I have a 96 Cavalier Z24. When I'm travelling on a highway where I can go 100 km/hour or more, after a few minutes travelling at this speed, the check engine light and the ETS light come on. At the same time when they come on I can feel a reduction in engine power for a split second, then the car seems fine. After an hour or so of city driving, the lights go off and stay off until I'm on the higway again. I was told it wasn't anything major to worry about.
Any thoughts on what this may be?
Thanks for any help or information.
Sherman
