Hi, i hope someone can help me with this!!!! well, im 17, and got my mustang bout 1 year ago. I found out about 8 months ago how to do a burnout, and did it a couple to alot of times! so then i noticed my tred was going down, so i stopped! but NOW that i kinda want to start up again just once in awhile, i all of a sudden cant do it anymore!!! D: so im wondering if my dad fooled around with the fuse box, and some how made it so my mustang will not stop in place and hold a burnout. if someone could help with telling me what happened/what to do, or with a picture, that would be great!! THANKS if you can help!
