My check engine light keeps coming on after I drive over 55mph. We had it into the dealership and they put it on some machine and all they came up with was a blown 15amp. We replaced the fuse and it did not fix the problem. We do live in a hilly area. Please help, as I worry about being stranded with my children.

Thanks Denise
