Also, when the motor was originally delivered and how many miles are on it? Is there any possible way to work back through the original buyer (i.e. if they are a Roush dealer, they might be able to get a response).
Lastly, do you think the cut out has to do with the FI? Maybe the FI electronics need to be swapped out. Has someone with FI expertise diagnosed the problem?

My tale is described in some detail elsewhere. I bought it at the Barrett Jackson auction in January. Alfredo did tell me that the previous owner had thought it was plagued with electrical problems and I do believe the FI control system is the cause of the rough running. I had it on a dyno and it was running real rich. The AFR matched from the Dyno and the FI controller, but it turned out to be TWO loose plug wires (as described above), so I'm replacing the 90* plug wires with 45* wires to keep tension off. We'll see. Sometimes it's simple things. It's definitely running rich - when I let off the accelerator I get small backfires from the pipes.
As for
oil, it gives a little puff of smoke when it starts, but so does my new Mustang. I also think it might be one of the valve covers leaking but haven't gotten there. I agree about the dye kit. That's on the list. The engine takes 11+qts!
