You have a lot of research and reading to do on these cars. I have an SC300 so for an SC400 the engine issues are different.

First thing I’d do would be to pull the ECU and send it out to be rebuilt/repaired/tested. Figure 1-2 week downtime for this. Check out SIA Engineering for this service.

If you are a DIY capable person then you have a nice project car to keep you busy. If not, do NOT go anywhere near a dealership but research a reputable independent mechanic with experience on SC4s to assess your needs.

Good luck.
