CHECK ENGINE LIGHT

2002 Buick Lesabre

Computer problem
2002 Buick Lesabre 6 cyl Two Wheel Drive Manual 101000 miles

My check engine light comes on after I refuel the car.
Is this a gas cap issue?

Hello,

Yes your gas cap can be the culprit. You say it comes on after you refuel does it go off after a while? Go by your local Auto Zone and have them pull codes. Post them here in forum.
