Collincoon,
I thought mine was bad and sent it to BBA Remanufacturing in the Boston area. Put it on my 300CE and the problem was still there. I then bought a used one with less miles, installed it and the problem still remains.
I have the the rebuilt one for sale. It was rewired and checked out by BBA. It has been sitting for a year in my garage. If interested, I can send pics and a copy of the invoice. It is yours for $200.
