Hi ASchaffer, My 98 Mustang GT is throwing the same codes as you indicated in one of your posts in 2004. I know that was a long time back, but that means you most likely found the cause and fixed it:) I am referring to the post below. forums.stangnet.com/476153-check-engine-code-what-does-mean.html Anything you may remember about the problem and how you fixed it would be great to know. Thanks, 98GT_Owner
