1993 Ford Explorer Question: Check engine light comes on when driving over 50mph and over 2000rpms



, Portland, OR, January 21, 2011, 02:47

My check engine light comes on when I reach 50mph on the freeway. If I slow down and let the rpms get below 2000, the light turns off. Around town it's fine, only happens on the freeway.

    Need to get the code that is being set by the check engine light, it will be there in the computer, even if the light is not currently illuminated.
