    If the check engine and brake lights are on, then how do you know there isn't a problem? These lights are indicating there is a problem, I would get the codes scanned and diagnosed.

    well the brake is obviously not on, and I didn't add that the rpms don't show and it says I need oil also.. it's obviously some kind of computer problem, but I will try the diagnostic check.

    I had the same problem. No matter what they did to fix it, (oxygen sensors, etc.) it would seem to be fixed, and then start all over again.

    Then I noticed it is temperature sensitive. If the car is parked on blacktop or it is a very hot day, this happens - if it is 10 degrees cooler, it does not.

    Since the error codes are heat sensitive, I am having the computer chip checked. I think the computer chip that monitors all the other systems in the car is itself bad. So it is reporting problems that do not exist whenever it gets hot
