Sounds like the battery is weak or the alternator isn't providing enough amps to keep the engine running and power the lights at the same time.

Testimonial: "thanks , it sounds logical. Should I replace the battery? The guy who owned it before me just replaced the alternator."
Unless your car has a governor installed on it (doubtful) your car will do more than 85mph. At various time the government in its infinite wisdom has set limits on what the speedometer can read as a way to discourage drivers sppeding and from seeing what their car can do as far as top speed. I mean what's the point of burying the speedometer and holding it when you can no longer tell how fast you are really going.

When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.
