How do I reset the service engine soon light on a

Try disconnecting the battery for 30 seconds, if that does not do it, Auto parts stores like Auto Zone can plug in a code reader, read the codes and then reset them.
This is a very common issue with these cars. I have replaced the gas cap on my '02 and that does not solve the problem - so save your money. If you do some digging around online you will find a lot of people experiencing the same thing. If I remember correctly, the fix is a good bit of labor involving dropping the gas tank. Good luck - mine goes on and off on a monthly basis at this point, but I don't have the time to explore the solution just yet.
My 2002 buick is the same story. However,mechanic replaced,fixed my gas gauge.after that sevice your engine lit up.It goes on,doesnt blink,shuts off,10,15 mi. Later,on again.the sevice engine light must be broke
