We see the steering angle sensors having issues on the older S2000s and it's sometimes can be cleaned and regressed.
In this case it had already been done and it's ready to be replaced.This S2000 also needed fluids as it may have never been done.
The other S2000 was here for a valve adjustment, it sure did need it. All intake valve were tight and exhaust valves loose.
Again, we did the fluids as well as they are often overlooked.
