So I took it in to ford and the tech said he didn't really want to take my money since it didn't have any signs that he could bill to warentee. He said he could scan it but with no light it would cost me $80 and most likely come back negative and he can't just go replacing parts. He said when he heard it it sounded fine (wasn't going quiet) but if it started to run rough, stall, or a light came on then to bring it back and he could do more investigate. I guess I will just live with it for now.
Cheers
Jeff
