Hello all, I have a minor irritant I'm trying to diagnose. While driving, I'm getting a clicking sound under the binnacle/from the footwell area. Occasionally, you can see corresponding movement in the speedometer. The previous owner told me that this was the speedometer cable and that occasionally it needs tightening to do away with the noise. I've since been told by another DeLorean owner that this explanation is flawed. Anyway, any idea what it may be and how to fix? It's the only rogue cabin noise I have, so I'd like to be rid of it! Thanks.
