My 91 CRX HF stalls when im driving over 10mph and throw it in neutral to coast to a light. when im under ten the RPMs don't drop under 750 so its good but over that the RPMs just keep dropping till it stalls. When this happens the battery light comes on right before the stall. When I got the car it did it and was throwing a code for ELD so I changed the under hood fuse box and it stopped. Then one day my battery got loose and I tightened it up and this started back. Some one told me maybe grounds but they seem decent or at least the two I could find did.

 

Have you checked your TPS?

Start there and try to rule that out as your problem.

 

Well turns out that all my ground on the granny lead to the negative post on the battery. So I grounded it and the problem stopped. Wish I had done the swap myself.

 

Turns out all the grounds on my transmission were connected to the negative post on the battery and not grounded. So I grounded them and it fixed. Wish I had done the swap myself.
