I had a similar problem. Does your cruise control work? If not then look under your hood on the ps. Youll see a vac line that runs beside your battery. Mine rubbed on the battery and put a hole in it. Take a peice of rubber hose and cut it long ways and put it over the line. Then electrical tape the hell out of it . Problem solved , for me anyway. Good luck.
