I don't think the ELD would be responsible for stuttering and stalling. I had a bad ELD on my civic and the only noticeable difference was that my CEL was illuminated.

In my civic the code for a ELD was P1298. There's a low and a high voltage code, so be careful. Also, in my 01 civic, the ELD was removable able to be purchased separately. In many cases a bad ELD will result in purchasing a new fuse box, since it's permanently attached in there.
