If it were a V8, you'd be peachy. I wouldn't think your fuel pressure would be a problem though. Let me move you over to the tech section, the resident genius and all around nice guy @jrichker can probably help you out.

What was the exact code number?

Spec would be 39 psi Code 86 means "adaptive limit reached:RICH" So I think you are on the right track that you might be a bit rich
