I am running MS WinXP SP3 with MS Security Essentials. I am not running Windows Defender or Windows Live OneCare. Why is MsMpEng.exe gobbling up so much resources when running? Does MSE use MsMpEng.exe also? If so, how do I minimize its impact?

Wrong forum. MSE discussions are here: http://social.answers.microsoft.com/Forums/en-US/category/mse - I can't move your post as the MSE forums are on a different back end.
That said, the most common reason for MSMPENG.exe consuming excessive CPU is a conflict.
Prior Security Software?
Any security software still installed?
A possible reason for this problem is that you have conflicting security software installed fully or partially on the PC. Remove all other security software from the PC.
You may need to use a cleanup tool to remove your prior security software:
Be sure to review this post:
Check list for installing Microsoft Security Essentials
If that fails to resolve the problem, open an email support case:
