Having problems with your Pontiac Grand Am ?

I have a 1990 Pontiac GrandAM. The "service engine soon" light comes on shortly after I start the engine. I have replaced the throttle position sensor, chacged the oil - does the service light mean I need a tune up, or does it indicate a specific problem?

Answers :

It actually gives you a code that indicates a specific problem. Take it to Auto Zone or Advance Auto or another Auto Parts store that offers to read the fault codes for free. Once you make the repair indicated by the code you will have to reset the vehicle computer to clear the code. You can do this by disconnecting the Negative battery cable for 60 seconds and then reconnect it.
