Are you talking about the check engine light or the little maintenence bar by the tach?
If its the little maintenence bar by the tach then it does that every 3,000 miles or so as per regualr maintenence schedule from the factory.
If its the Check Engine light then run the code on it and see what comes up.
My bet is you mean the regular maintenence bar and in that case i can't help but :lmfao:
