check engine light

What is your question?

Would that have ay thing to do with me putting 89 istead of 87 in it? I would guess it usually had 87. Is there an easy fail safe to make sure that it is the problem. I drove it home 80mph with no problems? no problems till it was super cold today.

No, I have never seen 87 vs 89 octane cause a Check Engine Light because vehicles have an octane adaptation mechanism that uses a knock sensor to adjust the ignition spark timing to the level of octane in the vehicle. here is an article to help explain what the Check Engine Light means http://repairpal.com/check-engine-light
