For about 2 weeks I have had this problem of when I let off the gas I get a high pitch ringing noise from the passenger side dash. Its only when I let off the gas. Its not the brakes or anything mechanical for sure. Any Ideas? I am about to make a 1000 make run each way in 6 days. Gotta get it figured out fast.

I have another problem also, but will start another thread in a sec.
