do u guys get a CEL when u exceeed the original speed limiter ? i was on the freeway last night adn right around 115 the CEL came on. just curious if it could be the speed , before i go out in the morning and check. thnx.

 

could be that your speedo cable might be getting old, thats the only thing i can think of that could go wrong speedometer related, cause those do go bad especially if its never been spun that fast

 

No, not usually.

Pull the code that the ECU has stored and see what it is.
