2003 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic 60100 miles
My engine makes a loud metallic noise when it is cold and it diminishes as the the engines warms up. I changed my upstream 02 senor about two weeks ago and I added some stop leak to my radiator because it had a small leak. Could this be causing the problem? I didn't have any problem prior to changes.
have the same problem?
